A Simple Interior Decomposition Model: Its Development And Application

A simple interior decomposition model composed of the product of two terms, a shielding-effectiveness term and a coupling- effectiveness term, has been developed that bounds the measured wire responses within a simple generic test object. A variety of modest to strong perturbations to the test object geometry and composition changed the response trend downward by at most 12 dB and typically only by 3-6 dB. Thus the model, called shielding effectiveness × coupling effectiveness (SEXCE), serves as a reasonable characterization of a broad range of generic geometries. It is useful in understanding the interior coupling response behavior and can be used as a predictive tool.
