Brewster angle of thermal diffusivity waves at an interface

In this work, we study the existence of the Brewster angle for thermal diffusivity waves. We analyze the propagation of plane thermal waves impinging upon an interface between two media. The condition of zero-reflection defines the Brewster angle. We demonstrate that the Brewster angle only exists for specific combinations of diffusivity and thermal conductivity of the incidence and transmission media.
