  In this work, we present a theoretical study of the dispersion of linearly
polarized light between two dielectric media separated by an anisotropic
two-dimensional (2D) material under oblique incidence. Assuming that the 2D
material is a conducting sheet of negligible thickness, generalized Fresnel
coefficients are derived as a function of usual quantities (e.g. refraction
indexes and scattering angles) and the anisotropic in-plane optical
conductivity of the interstitial 2D material. In particular, we analyzed the
modifications due to the 2D material of two classical optical phenomena: the
Brewster effect and the total internal reflection. As an application, our
general findings are particularized for uniaxially strained graphene. Effects
of a uniaxial strain on the Brewster angle and the reflectance (under total
internal reflection) are evaluated as a function of the magnitude and direction
of strain.
