Abstract
The design and description of a dual band electromagnetic (EM) absorber for the C-band and Ku-band are presented in this study paper. In the proposed structure the absorber is composed of two ring and four-square resonators. The Two ring resonators, four square resonators and ground of the proposed microwave metamaterial absorber are made of copper(annealed) with FR-4(lossy) serving as the substrate. The suggested structure has an absorption bandwidth of 400 MHz and 600 MHz with absorption peaks of 99.60% and 99.54% at resonant center frequencies of 7.42 GHz and 13.32 GHz respectively. The results demonstrated that such an absorber does have good absorption and is polarization-independent about large incident angles for both TE mode and TM mode in the two absorption bands
