A beam combiner, which can combine multiple Gaussian beams into a single one, has many important applications, such as high-power radar and weapon. In this paper, we propose a new scheme of the design of high-power beam combiner at millimeter wavelengths by using wire grids. The design tool is to combine a genetic algorithm (GA) for global optimization and an Ansoft HFSS for rigorous electromagnetic computation. The design method is described in detail and the optimized results are presented. Finally, a brief summary is given.
