This letter shows a method for approximately calculating the shielding effectiveness of a rectangular enclosure with thick multiple apertures. Numerical results illustrate the shielding effectiveness of the enclosure with various thicknesses and aperture spacings. This method is reasonably accurate up to 2/3 of the cutoff frequency associated with the longer aperture dimension. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 178–181, 2001.
