We exploit two phenomena for temporal metamaterials where the permittivity is changed from an isotropic case to an anisotropic tensor. We will show how such temporal variation of permittivity can lead to: (1) real-time change in the direction of energy propagation, and (2) under certain condition, to the temporal analogue of Brewster angle. We provide full physical insights of this phenomenon demonstrating, numerically and analytically, how it can be exploited for real time beam steering of electromagnetic waves.
