We investigate the Goos-H\"{a}nchen-like shifts for Dirac fermions in transmission through a monolayer graphene barrier. The lateral shifts, as the functions of the barrier's width and the incidence angle, can be negative and positive in…

Using the energy spectrum of graphene with spatially modulated potential, we study the Goos-H\"anshen shifts near extra Dirac points located at finite energy $\varepsilon=m\pi$, with $m$ integer. On both sides of such points, we show that…
