主　　题：absorber transverse absorption 

摘      要：An ultra-wideband metamaterial absorber is developed,which is polarized-insensitive and *** layers of square resistive films comprise the proposed *** optimal values of geometric parameters are obtained,such that the designed absorber can achieve an ultra-broadband absorption response from 4.73 to 39.04 GHz(relative bandwidth of 156.7%)for both transverse electricity and transverse magnetic ***,impedance matching theory and an equivalent circuit model are utilized for the absorption mechanism *** compatibility of equivalent circuit calculation results,together with both full-wave simulation and experimental results,demonstrates the excellent performance and applicability of the proposed metamaterial absorber.
