Negative refraction and reflection of Gaussian beam on two-dimensional photonic crystal slab
Abstract
The refraction and reflection of Gaussian beam on two-dimensional photonic crystal (2DPC) slab are studied by the finite-difference time-domain (FDTD) method. It is shown that 2DPC slab enables negative refraction, which is demystified by the distribution of Poynting vector directions and values inside the 2DPC. A negative Goos-Hanchen shift is also found in the simulation.
