Fig. 2From: Tunable and Anisotropic Dual-Band Metamaterial Absorber Using Elliptical Graphene-Black Phosphorus Pairsa Comparison of plasmonic responses between monolayer graphene (blue solid curve and blue dashed curve are overlapped), monolayer BP and graphene-BP pairs, and absorption spectra with different a (b), b (c), and td (d). The default parameters are a = 62 nm, b = 100 nm, td = 1.35 μm, t = 5 nm, and P = 250 nm, under normal incidenceBack to article page
