The electromagnetic fields are described with a series of circular cylindrical waves whose cutoff wavenumber and amplitudes are obtained by imposing the boundary conditions. The field-matching procedure is facilitated by a new line integral extendedover the closed contour and the use of the transformation between plane and circular waves. The conversion betweenthe different field representations is carried out by means of a Fast Fourier Transform (FFT), resulting in a very efficient method.}, url = {http://w3.iec.csic.es/ursi/articulos_coruna_2003/actas_pdf/SESION\%201/S1.\%20Aula\%202.2/1454\%20-\%20CALCULO.pdf}, author = {J A Ruiz-Cruz and Rebollar, J M} }
