Using integral equation methods to incorporate open area test site effects in finite modelling techniques

A method of making reliable predictions of electronic equipment on an open-area test site is demonstrated. The method utilises the ability of finite electromagnetic modelling techniques to make accurate predictions of propagation in and around enclosures, etc. It circumvents, however, the need for prohibitively large amounts of computer memory when incorporating the test site effects. Integral techniques are used to generate a transfer function which accounts for the ground plane interactions. This transfer function is specific to individual pieces of equipment, thus allowing complex interactions associated with a specific piece of equipment to be modelled quickly and accurately
