摘要

This paper presents simulation very simple structure of multi band metamaterial absorber at the microwave frequency band. The unit cell of the proposed structure consists of two copper rings at different radius, loaded onto FR4 substrate with 2.5 mm thick in order to achieve perfect multi absorption bands. The asymmetrical ring structure generally makes it sensitive to electromagnetic (EM) waves polarization. But the Penta-Perfect Metamaterial Absorber PPMMA proposed structure is capable to absorbs electromagnetic wave at wide range of incident EM wave. The CST simulated result of proposed PPMMA structure shows that the five-band realizes perfect metamaterial absorber for normal incident electromagnetic waves of 91.3%, 99.3%, 93.7%, 98.2%, and 97.4% at 12.25 GHz, 12.9 GHz, 16.15 GHz, 16.78 GHz, and 18.44 GHz of absorbance value respectively.
