摘要

Abstract

The study is devoted to the electrodynamic properties of composite materials based on AlN–5 wt % C (carbon black) or AlN–5 wt % C (diamond powder) and 5% molybdenum in the frequency range of 1–10 GHz. The materials were obtained by free sintering at a temperature of 1850°C. The results demonstrate that the real and imaginary parts of the relative permittivity of the composites containing carbon black and diamond powder with molybdenum at a frequency of 10 GHz are ɛ' ≈ 16.1, ɛ'' ≈ 4.3 and ɛ' ≈ 9.3, ɛ'' ≈ 0.7.
