Fig. 1From: Tunable and Anisotropic Dual-Band Metamaterial Absorber Using Elliptical Graphene-Black Phosphorus PairsA unit cell of the proposed absorber based on elliptical graphene-BP pairs. td and t are the thicknesses of the dielectric and insulator layer, respectively. a and b are the short axis and long axis of the ellipse. P is the periodic side length of the square unit cellBack to article page
