Broadband Radio Absorbing Structures with Small Reflection Coefficient

O. A. D’yakonova, Yu. N. Kazantsev

Abstract

Single- and two-layered broadband radio absorbing structures based on resistive threads are designed and investigated. The complex dielectric permittivity of a resistive thread as a function of the wavelength is investigated. A method for calculating the reflection coefficient of resistive-thread-based structures is proposed. By means of this method, experimental samples with reflection coefficient less than -15 dB for a two-layer structure, and less than -20 dB for a single-layer structure are obtained.
