Abstract :
Transverse electric (TE) wave transmission through slits on single and double metal plates of finite thickness is studied by using Galerkin´s method. It is observed that by either using a thick plate (for slit narrower than half a wavelength) or using double plates with slits laterally shifted (for slits wider than half a wavelength), the amount of power transmitted through the slits can be significantly reduced. These schemes can be applied to improve the shielding effectiveness of equipment cabinets
