22where T; (x) and T: (y) are triangular functions defined byand P; (x) and 11 (y) are pulse functions defined byIn the original problem, unknown aperture fields can be expressed as a sum of allpossible modes, including evanescent modesare the transverse electric and magnetic fields for the k-thT E and k-th T M mode across the aperture. 4k and A Aek are the complex amplitudes ofincident k-th mode to the aperture and B[1 ,,, and BAek are the complex amplitudes of reflectedk-th mode from the aperture. Same as in mode matching method calculation, indices h ande represent T E and T M modes, respectively.
