AB  - This study presents a new design for a two-layer insensitive of electromagnetic polarization
for dual-band based metamaterial absorber at X bands. The electromagnetic absorber proposed her consists
of a periodic unit cell of two circular ring resonator arrangement in a double layer. The proposed structure
resonates at two frequencies 2.62 and 2.82 GHz with absorptivity level 97.2 and 99.3%, respectively. It displays
insensitive of EM polarization performance for TE and TM polarization under oblique wave incidence. The
electric field and surface current distributions have been contemplated for improved comprehension mechanism
of the dual-band absorption. The manufactured of proposed absorber has been examined, the simulated results
and the experimental results are good agreement. This insensitive metamaterial absorber of electromagnetic
polarization with its simple of implementation and almost absorption can be utilized for radar applications.
