Abstract

THz wave emission in the cavity which contains the graphene-multilayer asymmetric hyperbolic metamaterials is investigated numerically using transfer matrix method. In was assumed that the gain saturation appears as the decrease of imaginary part of effective dielectric permittivity. Gain -loss balance predicts the intensity of THz lasing.
