A determination of propagation constants of symmetric planar waveguide modes in a frequency domain
In a new method of finding propagation constants of waveguide modes, the
 Fourier transform to wave equation is used. We change the differential equation by the
 integral one. Then we represent the latter equation in a discrete form and get the
 eigenvalue (square propagation...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | In a new method of finding propagation constants of waveguide modes, the
Fourier transform to wave equation is used. We change the differential equation by the
integral one. Then we represent the latter equation in a discrete form and get the
eigenvalue (square propagation constants)/eigenvector (the discrete Fourier transform of
appropriate fields of waveguide modes) problem. Usage of symmetry for symmetric
planar waveguides allows to expand opportunities of the new method essentially: to
reduce the time of numerical calculation almost triply without loss of analysis accuracy
or improve calculation accuracy.
