Sažetak
Planar, cylindrical and spherical patch antennas and periodic surfaces are frequently analyzed by means of the electric field integral equation and the moment method. The kernel of the integral operator is a Green's function, which is different for different structures. There are two basic approaches for determining the Green's function of general multilayer structures: either to analytically derive an expression for it and then to code this expression, or to develop a numerical routine for the complete calculation. The analytic approach requires less computer time than the numerical approach. However, it is a very laborious process to analytically determine the Green's functions for substrates with more than two layers. Therefore, in such cases it is convenient to use a numerical algorithm which determines the Green's function directly. Furthermore, the analytic approach requires often a new derivation of the Green's functions for a slightly different problem, such as for different number of layers or for different source locations inside the layers. The purpose of this paper is to present the algorithm, called G1DMULT, for calculating the Green's function in the spectral domain (representing a one-dimensional (1D) spatial domain) for planar, circular cylindrical and spherical multilayer structures. Furthermore, we will describe several programs for analyzing cylindrical and spherical antennas and scatterers which use G1DMULT as a core subroutine.
