Investigations on Shaped Mirror Systems in Quasi-Optical Mode Converters Based on Irradiance Moments Method
International Journal of Antennas and Propagation
A method of transforming high-order Gaussian beams (GBs) mode into circular symmetry fundamental Gaussian beam (FGB) mode with arbitrary waist size is presented using irradiance moments method in quasi-optical (QO) mode converters. The double shaped mirrors correcting amplitude and phase simultaneously are generated by a single incidence irradiance sampling data and known ideal output FGB taking advantage of linear moment matching technique and Fresnel diffraction theory, which can be applieddoi:10.1155/2016/8043042 fatcat:7h6jkkmj4ngr5p2qu224ogha4i
