Abstract :
The design of a high-frequency dichroic plate consisting of an electrically thick self-supporting metallic mesh that can be used in a linearly polarized quasi-optical system at high angles of incidence is described. The measured and computed performance of a 2.5-in-aperture mesh is given. This mesh has a 3-dB cutoff frequency of 875 GHz and less than 0.75 dB of transmission loss from 950-1350 GHz at incidence angles of 0, 30, and 45 degrees . The results of a multimode waveguide analysis corroborate the measured data.<>
