There are many potentially interesting phenomena that can be obtained with wave refraction in the “wrong” direction, what is commonly now referred to as negative refraction. All sorts of physically new operations and devices come to mind, such as ne
We have a new idea to infer the refractive index for the extraordinary ray (the Poynting vector) in double refraction crystals at any incidence and arbitrary orientation of the optical axis. The expression for the ray index is given. We confirm that
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 distrib
