Abstract [en]

The approach presented in this chapter is based on the description of the scattering properties of the discontinuities in free space and regular wave-guiding structures in terms of transform operators. These transform operators are qualitatively the same for all scatterers that are characterized by the discrete spatial spectrum of the signal's evolutionary basis. By the notion of scatterers with discrete spectrum we imply such electromagnetic objects that have solutions of the corresponding boundary value problems in the form of a series of spherical or cylindrical harmonics, or of plane wave or waveguide modes. In FD this approach is known as the generalized scattering-matrix technique and is widely used nowadays in the context of automatic simulation and design.
