Аннотация
It has been suggested a method for identifying and separating magnetic and electric microwave resonance responses of chiral conductive elements through reflection in standing- and travelling wave regime. Unique properties of metamaterials are mainly connected with magnetic resonance, which finds an application for creation of magnetic metamaterials and left handed media. So, separating magnetic and electric resonances and identifying magnetic resonance are important having regard to many different kinds of inclusions and great number of different types resonances, as well difficulties of direct measurements of permeability and permittivity. Going methods are based on transmission T analyzes [1, 2]. Separation of magnetic and electric resonances has been suggested and implemented from comparison of T in cutoff and conventional waveguides [1]. Authors [2] separate double split Ring Resonance (RR) and Dipole Resonance (DR) by comparison of T for DSR and closed rings and do not separate magnetic and electric resonances due to ring currents. In this paper it has been experimentally observed in waveguide and numerically confirmed for free space that magnetic and electric resonances in metamaterial elements show dramatically different resonance curves of reflection R (module and phase) [3]. These distinctions allow to identifying the magnetic resonance as applied to different kinds of inclusions and offer perspective of new applications in the field of broadband matching of absorbers by no traditional quarter-wave effects. Matching layer is array of meta-inclusions excited by microwave magnetic field. Use of varactor-loaded meta-inclusions opens a possibility of electrically controlled matching of absorber
