ABSTRACT:
Systems and methods are provided that allow transmission of an electromagnetic wave in and through a periodic multilayered photonic device. The photonic device preferably is a periodic stack of plane-parallel layers with at least one them displaying dielectric anisotropy with a principle anisotropic axis forming an oblique angle with the normal to the layers. The wave obliquely incident on the surface of the device can be almost completely converted into an axially frozen mode characterized by a significantly increased amplitude, decreased group velocity normal to the incident surface and increased energy flux substantially tangential to the incident surface. The photonic device can be used in numerous applications over a wide range of frequencies up to and including the ultraviolet spectrum. The photonic device can be further configured with a deflection device which substantially increases the operational frequency range of the photonic device.
