Specificities of the Microwave Reflection Coefficients of Magnetically Excited Chiral and Ring Conductive Elements for Separation of Magnetic and Electric Responses and Broadband Matching of Radio Absorbing Composites

Abstract

Distinctive features of the resonance responses of the reflection of microwaves from conducting double and single split-ring resonators, making it possible to distinguish between the magnetic and electric responses and identify the magnetic response of elements of different shapes, are studied experimentally in a rectangular waveguide and numerically in free space. It is shown that the specificities of the frequency dependence of the magnetic response can be used for broadband matching of radio absorbing composites.
