Attenuation of microwave radiation at 34.09–34.19 GHz in a composite material based on diamond micron powder structured by a nanocarbon binder vapor-deposited at subatmospheric pressure

Abstract

Microwave attenuation in samples of a diamond micron powder based composite material structured by a nanocarbon binder vapor-deposited at subatmospheric pressure is measured at frequencies of 34.09 to 34.19 GHz in a cylindrical resonator at H₁₁₁ mode. Return losses are determined from the measurements. Volume resistivity of the samples is measured. The potential of using diamond-containing structured composite materials as microwave radiation absorbers is demonstrated.
