摘要：
Radio absorbing materials based on polyurethane filled with multicomponent particles of MnZn ferrite coated by polyaniline with different conductivity and morphology were prepared. Complex permittivity and permeability spectra of composites were studied in the frequency range from 1 MHz to 3 GHz. Absorption characteristics of single-layer metal-backed radio absorbers based on the obtained materials are numerically estimated. The possibility of attaining the matching condition and altering the operating frequency range of the absorbers from hundreds MHz up to 2 GHz via variation of polyaniline overlayer properties is demonstrated.
