S. Caorsi et al., ELECTROMAGNETIC SCATTERING BY A MULTILAYER ELLIPTIC CYLINDER UNDER TRANSVERSE-MAGNETIC ILLUMINATION - SERIES SOLUTION IN TERMS OF MATHIEU FUNCTIONS, IEEE transactions on antennas and propagation, 45(6), 1997, pp. 926-935
An exact solution to the electromagnetic scattering by a dielectric mu
ltilayer infinite cylinder of elliptic cross section is proposed, The
interfaces between different media, which are assumed to be lossless a
nd nonmagnetic, are confocal elliptic cylinders. Starting from the ser
ies expansions in terms of Mathieu functions, an efficient recursive p
rocedure for the computation of fields and radar cross sections per un
it length under a transverse-magnetic illumination is developed, The m
athematical formulation is detailed and some numerical results are pro
vided.
