Abstract :
We analyzed the mesh reflecting surfaces by using MoM with RWG basis and testing functions, which solve integral equations with periodic Green´s function. Computed transmission losses approximately matched with the measured ones, even though our surface-patch models had single strip width. Detailed analysis on the difference between computed and measured transmission loss is under study The analysis of transmission loss for various polarization and incident angles indicated that the electrical characteristics of single satin mesh were better than those of single atlas mesh.
