A method of moment program that can be used for analysing planar conducting structures (such as e.g. printed circuit boards) in free space or on a grounded dielectric substrate.
The program computes the current distribution, in the frequency domain, on the conducting patches due to either exciting voltage sources or an exciting incident plane wave.
Also the near fields and far fields can be computed. Impedance elements that serve as models for discrete elements (R, L and C) can be placed on the structure at arbitrary positions.
The structure is easily defined by drawing it on the screen with the mouse. Several different ways of visualising computed quantities can be used in the program; 3D plot of the current distribution, vector plot of current distribution and polar plot of radiation patterns.
The program has a help file.
