An extension of the biconjugate gradient fast Fourier transform (BiCG-FFT) method is proposed for the calculation of the shielding effectiveness of perfectly electric conducting (PEC) rectangular boxes with a large number of apertures. The unknowns remain confined on the surfaces. Considerable saving in memory and calculation time is obtained.
