Abstrakt: | Polymer composites filled with carbonyl iron are considered. A method is proposed for extending the operating frequency band of such radio absorbers with the help of band-reflection frequency-selective surfaces (FSSs). A functional relationship between the reflection characteristics of a radio absorber and the generalized characteristics of an FSS?the resonance frequency and Q factor?is established. On the basis of the rigorous theory of integral equations, programs are developed for computation of the reflection coefficient of a radio absorber with an FSS implemented as a biperiodic lattice with ring elements. The reflection coefficients of a series of samples are measured in the frequency band 1?10 GHz. | ||||||||||
