| Circular polarization is one of microwave equipment with broad application.its the mostly function is switch linearly - polarized wave into circular polarized wave.grating- circular polarization is one of circular polarization,its advantage is simple structure and ease of processing.it is prone to expand high power and high efficiency range.because circular polarization have expand application.. Paper research grating parameter and performance.Firstly,the paper confirm grating's size base on grating circular polarization's basic theory. Then, establish electric field and magnetic field matching equation of space and plate wave-guide. program about slice-grating- circular polarization..analyse its transmit characteristic and polarization characteristic. gained same data with literature. Paper based cascade scatter matrix field matching equation. program currency frame grating programme.obtain several design project of high power and high efficiency grating- circular polarization. |
