Enhanced-Selectivity Microwave Plasma Gratings With Graded Optical Excitation

摘要

The paper reports a new method of producing enhanced-selectivity microwave plasma gratings by the application of longitudinally graded illumination generated from a computer-controlled LED array. The detailed analysis of related grating reflections, bandwidth, and arrangement-specific photometric situation yields user-oriented results for creating best-performance light-induced periodic waveguide structures with an engineered excitation profile. Experimental investigations confirm the theory.
