Summary:
In this study, the problem of electromagnetic coupling through slits in two conducting parallel-plates is studied for the case that the structure is illuminated by a TE (to the slit axis) polarized plane wave with main interest on the understanding about maximum transmission mechanism. It is observed that the maximum of the normalized transmitted power with respect to the incident power density becomes 1/π wavelengths, irrespective of the slit widths and the incident angle of the TE wave, when the distance between the slitted conducting parallel-plates is much smaller than the wavelength. For the case that the slit is fed by a parallel-plate waveguide (PPW), the transmitted power beyond the slitperforated conducting plates is maximized for the case that the cavity formed between the edges of the slits is resonated. In addition, the equivalent conductance of the coupling slit for the case of maximum transmission is close to that for the narrow slit, 1/120λ0 .
