A novel wide band multilayer metamaterial absorber with high absorption rate and potential applications in multiple fields has been proposed.
A novel wide band multilayer metamaterial absorber with unit cell of centre-spin structure is proposed, which has a high absorption rate of up to 90% in the 2.2 to 5.2 GHz frequency range. We use equivalent impedance matching theory and characteristic mode theory(CMA) to analyze the characteristics and mechanism of the absorber, and verify the correctness of the absorber design through experiments.With the advantages of thin thickness, simple structure, insensitivity to polarization, and good absorption in a wide-angle range, the absorber has a certain application value in antenna, military radar target stealth, electromagnetic compatibility, and other fields.
