Comparison of slit transmittances between metal plates at terahertz range and PEC plate

The behavior of power transmission of a normally incidence plane wave with TM polarization through subwavelength slits on Ag and Au plates from 1.2 THz to 200 THz is investigated for various plate thicknesses. The transmission patterns versus plate thickness by using mode matching technique are contrasted to those of a slit on perfectly conducting plate. The transmission physics at low frequency is similar to that of PEC case, while the transmittances at higher frequency do not follow that of PEC.
