Optimisation of a simple equivalent dipole model to include edge effects

An approach that offers a simplified approximation for electromagnetic field (EM) emissions as a result of the finiteness of an EM scatterer is discussed. The scattering effects of a finite perfect electric conductor (PEC) which comprises reflection and diffraction are computed using the equivalent dipole model. The optimum placement of the equivalent dipoles is evaluated and shown that the solution is valid over a large frequency range or for time domain simulations.
