Abstract
Abstract Optical systems constructed of plasma matter. In particular optical systems such as radiation shields, reflectors, and shaped optical media in the form or function of optical lenses, optical polarizing devices, analogues to gratings and the like. Also disclosed are non-linear optical devices which function by a gradual, periodic, or abrupt change in optical properties of the optical medium. The said devices are constructed of plasma or other states matter, for example solid matter, semi-solid matter, fluids or combination thereof.
