Abstract
A metamaterial based subwavelength microwave absorber is presented in this paper. The proposed structure is resonating at five distinctive frequencies of 2.82 GHz, 6.93 GHz, 9.74 GHz, 10.60 GHz, and 14.13 GHz with 99.54 %, 74.93 %, 99.50 %, 99.79 %, and 99.66 % absorptivity, respectively. The unit cell of the proposed absorber fits in a small volume of 12 mm × 12 mm × 1.6 mm. The proposed structure is polarization insensitive and performs well up to an incidence angle of 60° for TE and TM polarized wave. The absorption phenomenon of the proposed absorber is investigated by surface current distribution and power loss density plots.
