摘要
In this letter, we propose a novel ultrathin polarization-independent electromagnetic absorber and provide numerical simulation and experimental verification of the absorbing properties. The proposed absorber takes the form of periodic resistive resonance loops. The resonance loops, as a sort of effective loss magnetic currents, are placed in close proximity to the grounded surface. Numerical simulated and experimental results show that the overall thickness of the proposed structure is much less than centesimal wavelength, and the absorptivity at different incidences is kept well.
