Goos-Hänchen and Imbert-Fedorov Shifts for Epsilon-Near-Zero Materials (1911.08999v1)
Published 20 Nov 2019 in physics.optics
Abstract: We investigate the reflection of a Gaussian beam impinging upon the surface of an epsilon-near-zero (ENZ) medium. In particular, we discuss the occurrence of Goos-H\"anchen and Imbert-Fedorov shifts. Our calculations reveal that spatial shifts are significantly enhanced owing to the ENZ nature of the medium, and that their value and angular position can be tuned by tuning the plasma frequency of the medium.
