FIELD-DYNAMICS IN A PARALLEL-PLATE SIMULATOR

Establishing the properties of the excitation field is critical in the process of evaluating the electromagnetic susceptibility of a piece o f equipment, This paper examines the electric and magnetic fields gene rated in and around a large parallel plate simulator, both numerically , using the numerical electromagnetic code (NEC) [1], and experimental ly, in an effort to better understand the field dynamics inherent to t he system. Comparison of the computed and measured results shows good correlation. In addition, the contribution of the three sections (Fron t taper, middle section, and back taper) of the simulator are numerica lly isolated and the contribution of each to the overall field wavesha pe is discussed. The optimal positioning of a test object is determine d based on the above results.
