Abstract:

In this report the derivation of the Method of Equivalent Currents is given. This method can be used to compute the diffraction of plane waves by edges. A computation of this sort is necessary in addition to a scattering computation using Physical Optics or Geometrical Optics, because these last techniques neglect edge effects by definition. The reason that the Method of Equivalent Currents is chosen is because it is a powerful method, valid at almost all incidence and scattering aspects. Some of the few remaining singularities of the method can be removed in a way described in this report as well. Some interesting comparisons with measured data will be given in order to show the capabilities and shortcomings of the method.
