This paper presents the design, fabrication and measure- ment of a polarization insensitive microwave absorber based on meta- material. The unit cell of the metamaterial consists of four-fold rota- tional symmetric electric resonator and cross structure printed on each side of a print circuit board to realize both electric and magnetic reso- nances to achieve e-cient absorption of the incident microwave energy. Both the full wave electromagnetic simulation and the measurement on the fabricated absorber demonstrate high microwave absorption up to 97% for difierent polarized incident electromagnetic waves. To under- stand the mechanism, analysis is carried out for the electromagnetic fleld distribution at the resonance frequency which reveals the work- ing mode of the metamaterial absorber. Moreover, it is verifled by experiment that the absorption of this kind of metamaterial absorber remains over 90% with wide incident angle ranging from 0 - to 60 - for both transverse electric wave and transverse magnetic wave.
