A complete electrodynamic model and a synthesis algorithm of energy compressors have been developed for the first time. The
theoretical problems have been solved that occur when constructing these structures on the basis of two connected in series axially-
symmetrical open waveguide resonators (‘storage + switch’). Figs. 8. Ref.: 18 titles.
Key words: energy compressor, open resonator, waveguide, synthesis.
Microwave energy compressors (see, for
example, [1–4]) contain, as a rule, two resonant units:
one of them is meant for accumulating an input
energy, while another plays the role of a switch,
which closes the output section at the time of energy
accumulation and opens it at the moment of
discharge. The optimal matching of these units is
rather complicated electrodynamic problem. Its
solution has to provide the following:
– coincidence (adjacency) of the operating
(resonance) frequencies AkRe and LkRe
of the storage volume and the switch;
– required dynamics and the limits of the field
intensity growth for operating oscillations in
the storage resonator and in the switch (both
are determined by the Q-factors of the
oscillations in the corresponding open or
closed resonators, namely, by the values
AkIm and LkIm , by a deviation of the
central frequency ck of a quasi-
monochromatic exciting pulse from
compressor’s operating frequency wk , and
by parameters of a coupling window
between the feed line and the storage
volume);
– the possibility of fast discharge (the
eigenfrequencies LAk of the system
‘unlocked storage volume’ may not be
located in the vicinity of wk in the complex
plane of variable k ).
It is evident that all basic characteristics of the
open system ‘feed waveguide–coupling window–
storage–switch–output waveguide’ are interrelated
parameters. Variations in any of them cause changes
whose effect cannot be estimated simply
experimentally, in the context of simplified,
approximate models, although these changes can
deteriorate essentially the system characteristics. The
computational experiment based on a rigorous
mathematical simulation offers evident advantages
over the traditional approaches to the synthesis of the
devices of this kind. It simplifies the optimization of
the synthesized structures allowing one to examine
efficiently a lot of options [5] and to analyze in detail
the physical processes taking place in compressors.
1. Simulation and Analysis, Model
Synthesis. One section in [6] is devoted to the
development of the general approach to solving
problems of model synthesis of resonant quasi-
optical devices. As applied to microwave energy
compressors, this approach has been implemented for
the first time in [7]. It includes: estimation of a range
of functional capabilities of separate elements and
matching of these capabilities with the functional
area of the unit as a whole; construction of the
mathematical model of the unit and its
electrodynamic analysis. For solving the problems
arising at these stages (as a rule, these are open
boundary-value or initial boundary-value problems,
i.e. the problems with infinite analysis domain along
one or several axes) we use the rather powerful and
universal time-domain methods [8]. These algorithms
supplied with the original ‘fully absorbing’ boundary
conditions [5,9,10] allows one to carry out the
analysis in bounded spatial domains for any time
intervals and to obtain reliable numerical data
describing transient processes under resonant
conditions. It should be noted that the well-known
heuristic and approximate algorithms truncating a
computational domain, which are based mainly on
the application of the Absorbing Boundary
Conditions [11,12] and Perfectly Matched
Layers [13] (occurring in practically all widespread
software packets for electrodynamics) don’t assure
correct results in the case of resonant wave
scattering.
The developed algorithms have been
implemented in the packets of special-purpose
computer programs for simulation and analysis of
energy compressors and resonant radiators of high-
power short radio pulses with arbitrary types of
storage units (waveguide and open resonators with
metal, semitransparent, and frequency-selective
167
mirrors) and switches (distributed grating-type
switches for compressors on multimode waveguides
and for resonant radiators; interference and resonant
switches for compressors with single-mode output
waveguides).
Although compressors are various in
constructions and hence the development of separate
details during the analysis and synthesis procedures
requires an individual approach, all basic stages of
the scheme presented below are implementable in
many practically interesting cases.
Consider a synthesis problem of axially-
symmetrical ( 0≡∂∂ φ ) direct-flow compressors on
the sections of circular and coaxial circular
waveguides with the single-mode input and output
ports on TM01- and TEM-waves, respectively. The
wall loss is neglected. The compressor characteristics
obtained (the degree of compression, i.e. a ratio
between input and output pulse durations; the
efficiency, i.e. a ratio between the energy stored in
the output and input pulses; the power gain, i.e. a
product of the degree of compression and the
efficiency) are not optimal. At this stage, it was
important to develop a synthesis algorithm proper, in
other words, to formulate the theoretical problems
that occur when constructing compressors and to
determine the methods of solution.
In the paper, the SI system of units is used.
The variable t is the product of the real time by the
velocity of light in free space and has the dimensions
of length. We drop all dimensions. In the analysis
that follow, λπ2=k is the wavenumber (a
frequency parameter or a frequency), λ is the
wavelength in free space, ε and 0σ are the relative
permittivity and specific conductivity; ρ , φ , z are
the cylindrical coordinates, { }zEEEE ,, φρ= and
{ }zHHHH ,, φρ= are the electric and magnetic
field vectors, { }zg ,ρ= is a point in the two-
dimensional space, jL are the virtual boundaries of
the computational domain LQ , S is the boundary of
the perfectly conducting parts of the compressor;
( )tzn ,ρν are the space-time amplitudes of ρE -
components of pulsed waves. The geometrical
parameters in the model problems under
consideration are given in meters, however, all the
results obtained here can be easily recalculated for
other geometrically similar structures.
2. Algorithm of the Model Synthesis of an
Energy Compressor. The frequency properties of
the open or closed resonator considered as an
accumulator of energy can be determined by the
time-domain methods from the response of this
resonator on the excitation by a broadband signal
[5,14,15]. Let, at first, the pulsed TM01-wave

excites a storage unit with the closed (Fig. 1, a) and
open (Fig. 1, b) output channel. The central
frequency of the signal ( )tgU i , is 4,3=ck ;
parameters 1,1=∆k , 300 =T , and 400=T
determine its spectral band ( 5,43,2 << k ), a delay

the pulse crosses the virtual boundary 1L in the
plane 0=z of a cross-section of the input
waveguide),

here on ( )kf stands for the Fourier transform of the
function ( )tf ). In the input circular waveguide

only principal TM01- and TEM-waves propagate over
the frequency range considered. In the central
circular waveguide (in the storage unit, 56,12 =a
and 0,62 =c ), initially only TM01-wave is
propagating (up to the frequency 53,3≈k ), and then
TM02-wave arises. A beyond-cutoff aperture
( 8,4<k ) separates the input waveguide and the
storage.
Approximate values for real parts of
complex eigen frequencies Ak of the storage with
the locked output waveguide can be determined from
the dynamics in variation of ( )kR11arg φ , where
( )kR11
φ is the conversion factor of the incident TM01-
wave into the wave reflected from the virtual
boundary 1L with respect to φH -component: in the
vicinity of resonant points AkRe the dynamic-
phase effect [16] is realized. Approximate values for
real parts of complex eigen frequencies of the storage
with unlocked output channel is determined from the
resonance spikes of the curve ( )kR11
φ . Let us take
two values of AkRe ( 72,2Re ≈Ak and
17,4Re ≈Ak ) from nine values found, one for an
oscillation on TM01-wave and another for TM02-wave.
This kind of selection is dictated, as a rule, by a
synthesis task (the acceptable operation frequency
range) and by the requirement of a fast discharge.

Characteristics of the free oscillations
associated with the selected values AkRe can be
defined more exactly from the response of the
storage volume on the excitation by a quasi-
monochromatic signal with the central frequency
Ac kk Re= [14,15]. For the results presented in

1gg = and 2gg = corresponding to the antinodes

728,2Re ≈Ak and 172,4Re ≈Ak .
When exciting the storage with the open
output channel (Fig. 3) by a quasi-monochromatic
wave ( )tgU i , : ( ) ( )tFt 21 ,0 =ρν , 172,4=ck ,
5,00 =T , ( ) 9,999551,0: −−−tP (TM025-
oscillation is excited in the storage volume), the field
intensity increases and then (at 100>t ) decreases
gradually (Fig. 3, b). The situation with TM015-
oscillation (Fig. 3, c) is much better – this oscillation
we choose as the storage operating oscillation.
At the next step, we select a design of the
switch, whose attachment to the open port 3L
(Fig. 4, a) will not change substantially the
electrodynamic characteristics of the storage at the
frequency 728,2Re ≈= Akk . As a switch, the slot
resonator (see the right-hand part of Fig. 4, a and
[17]) has been chosen. This resonator almost
completely locks the output coaxial waveguide at
728,2=k (Fig. 4, b). The resonators of this type are
easily tunable on the required operating frequency by
choosing the slot depth. By varying the slot width,
we can control the rate of rise of zE -component to
select the value, which results in a discharge [17].
With the chosen construction (Fig. 5, a), the
requirement ( ) 0Re,2 =∈ AkzE Lρ (which ensures
electrodynamic equivalency between the storage with
the closed output waveguide (Fig. 1, a) and the
compressor as a whole (Fig. 5, a)) can be easily
satisfied at the frequency 728,2Re ≈= Akk by
varying the distance between the boundaries 2L and
3L . For the slot resonator shown in Fig. 4, a, the
reflection coefficient for ρE -component at
728,2=k is ( ) ( )ikR 6731,0exp9961,000 −≈ρ .
Under these conditions, the requirement
( ) 0Re,2 =∈ AkzE Lρ can be replaced by the
following: the argument of the reflection coefficient
00
ρR , being translated onto the boundary 2L , must
be equal to π± [18]. This requirement can be
satisfied by placing between the boundaries 2L and
3L a section of a regular coaxial waveguide of
length

However, the behavior of the function ( )tgH ,φ at

instead of the regular accumulation of the energy we

When the zE -component reaches the specified

function ( )t0σ , 40014000 << t , simulates the
discharge. The discharge transforms a slot resonator
into a section of a coaxial waveguide with a weak

All accumulated energy is released through the port
4L in a time equal to twice length of the compressor
(see Fig. 8; the distance between the boundaries 1L
and 4L is 8,9 ). The efficient duration of the input
signal is 40001 =iT ( 40000 ≤< t ), while the
duration of the signal resulting from compression is

These data are sufficient for calculating the basic
characteristics of the synthesized compressor: the
degree of compression 19041 ≈= si TTβ , the
efficiency 51,014 ≈= is WWη , and the power
amplification 97≈= βηϑ .
4. Conclusion. The model synthesis of
energy compressors and radiators of high-power
short radio pulses is bound to be based on universal
and efficient algorithms for solving electrodynamic
problems that represent properly the transient
processes under resonant conditions. The algorithms
of this kind and the packages of specialized computer
programs have been developed by the authors and
used for the solution of a set of theoretical problems
associated with the analysis and synthesis of energy
compressors in the form of two axially-symmetrical
open waveguide resonators placed in series. The
basic stages of the model synthesis are described in
detail and supported by numerical results.
