Description
Summary:The results of measuring the attenuation of the microwave radiation in samples: composite materials based on ASM 5/3 diamond micron powder (1) and nanodiamond (2) structured with carbon binder at a subatmospheric pressure and ceramic materials based on aluminum nitride (AlN) are presented. The attenuation of the microwave radiation is measured at frequencies of 33.4–33.6 GHz in a cylindrical resonator at  the H111 mode. The potential of using composite diamond-containing materials as microwave radiation volume absorbers is demonstrated. Comparison of specific attenuation in ACM 5/3-based and nanodiamond-based composites and in ceramic materials based on AlN (AN-38M, AN-50KK, AN-5C) is carried out. The specific attenuation of the microwave radiation in the composite based on nanodiamond is 1.3 times less than in the material AN-50KK but 1.4 times more than in the material AN-38M.
