Abstract: Waveguide circular polarizer using adjustable metal screws is designed for a project that studies ellipsometry and its device at microwave frequencies. A new design method is used based on theoretical analysis. The optimal design is found via simulation with Ansoft HFSS, and samples are made. Measurements show good performance of the samples.

Key words: axis ratio, metal screws to adjust, circular polarizer
