ABSTRACT

We proposed the model of a terahertz metamaterial absorber composed of metallic honeycomb cells joined by a cross in the center, a dielectric layer and a metallic substrate. The simulation shows that the designed metamaterial absorber has six distinct absorption peaks at 18.306; 19.836; 26.211; 28.302; 29.628 and 34.762 Terahertz with absorption rates of 97%; 98.6%; 99.3%; 97.7%; 99.8% and 94.3% respectively. The angular study of the system revealed that it remains a high absorption metamaterial absorber under both transverse electric and magnetic configurations.
