- Abstract
This paper presents the analysis of dual-band metamaterial perfect absorber (MPA) with nearly polarization-independent in X-band frequency. The resonating elements are designed using a rectangular ring structure, a slotted cross-structure, and a cross-structure. The resonating elements are printed on the top surface of FR4 substrate, while a full copper layer is printed at the opposite surface. The performance of the dual-band MPA is observed using CST software. From simulation, the proposed structure achieves almost perfect absorbance, which is 99.31 and 97.37% at 8 and 12 GHz, respectively, for normal incident electromagnetic wave. For oblique incident angles, it is observed that the operating angle (50% absorption limit) is 77° for both TE and TM polarizations.
