Magnetic response at visible and near-infrared frequencies from black phosphorus sheet arrays

We study theoretically optical properties of black phosphorus (BP) sheet arrays being embedded in the dielectric multilayer structure using transfer-matrix method. It is found that the dielectric multilayer structures containing BP sheet arrays can exhibit rich optical properties. In some frequency regions, strong anisotropy appears for the scattering and absorption of polarized waves. Thus, they can be used as the selective absorption materials for two kinds of polarized wave. In contrast, in some visible and near-infrared frequency regions, low absorption and strong magnetic response have been observed. This means that they can be also used as good magnetic response materials at visible and near-infrared frequencies. Our results could find applications in various control of polarized waves.
