This converter features a dimpled-wall launcher and employs a two-stage perturbation method based on coupled mode theory, complemented by a specialized mirror system. MATLAB code was developed to analyze the electromagnetic field in the launcher wall and mirror configuration. The radiation field emitted by the launcher is evaluated in free space, and the mirror system consists of a quasi-elliptical mirror, an elliptical mirror, and a parabolic mirror to ensure effective phase correction. The simulation results show that after phase correction, the scalar Gaussian mode content and vector Gaussian mode content of the output window reach 98.3% and 96.0%, respectively.
