ABSTRACT


Electromagnetic compatibility testing standards and regulations have become commonplace in industry. In order to ensure that one electronic device does not interfere with the functional behavior of another, governments and other agencies impose regulations on the radiated electromagnetic emissions of electronic devices. In the automotive industry, the Comite International Special Des Perturbations Radioelectriques (CISPR) organization regulates the allowable radiated emissions from an electronic module to be used in automobiles sold in Europe. A specific testing setup is required by CISPR to perform the regulatory measurements. This thesis presents a numerical model of the testing setup that can be used to predict the effects of altering the testing setup on the measurements of a module's radiated emissions. The numerical model is compared to an experimental setup constructed at MSU which also models the CISPR measurement setup. This experimental setup will help verify the numerical model's ability to predict the effects of varying certain physical parameters of the testing setup.
