Frequency characteristics of plane parallel Fabry–Perot cavities with square aperture metal mesh mirrors are studied theoretically using the finite-difference time-domain (FDTD) method. The use of Floquet boundary conditions enables us to reduce the size of the computational domain to one unit periodic volume. Metal losses are taken into account and implemented with first-order surface impedance boundary conditions (SIBCs). We show their effects on the transmission coefficient of cavities with various grid parameters and illuminated by a normally incident plane wave in the 60 GHz band.
