Abstract. We present a design for a polarization insensitive metamaterial absorber at 9.5 GHz by utilizing properly arranged resonant unit cells with orthogonal polarization sensitivity. Full-wave electromagnetic simulation demonstrates nearly perfect microwave absorption, which has been verified by experimental measurement with a maximum absorption of about 92% for incident wave with different polarizations. Furthermore, we find such a metamaterial thin absorber could work for a wide incident angle ranging from 0° to 50° with absorption no less than 80% for both the transverse electric mode and transverse magnetic mode.
