Abstract :
A study of the effectiveness of a finite-sized image plane in reducing the amplitude of the radiated emissions due to electric currents flowing near the plane is presented. The method of moments is utilized to examine how well a finite-sized image plane approximates an infinite plane and to analyze the effects of the dimensions of the image plane on the radiated emissions. A 2-D and 3-D analysis is included with similar conclusions drawn in both cases. In addition, measured data are presented which confirm the results of the numerical study
