Cálculo del campo difractado por objetos cilíndricos metálicos o multidieléctricos al incidir sobre ellos una onda

Abstract

A method is described for calculating the scattered fields from conducting bodies and concentric multilayered cylinders, when they are illuminated by a wave with no z-axis variation. The method is based upon descomposition of a vawe in a cylindrical wave series centered in the object, so that contour conditions can be applied. The exact scattered fields are calculated via Fast Fourier Transform routines. A generalisation of the method can lead to computation of fields scattered by separated single cylinders and cylinders containing non-concentric cylinders.
