Optimization of optical communication window mesh through full-wave analysis of periodic mesh

In order to develop an optical communication window mesh with good optical transmittance and shielding effectiveness at the same time, models were established for the shielding effectiveness and optical transmittance of optical communication window mesh, verified through experiments, and used to run full-wave analyses. The effect of period and linewidth of mesh on the shielding effectiveness and optical transmittance of optical communication window mesh was investigated through simulation. Simulation results indicated that better optical transmittance can be achieved using optical communication window mesh with high porosity and finer linewidth while the given shielding effectiveness requirement is satisfied.
