Research Topics


The objective of this project is to provide a comparative evaulation of six key techniques utilized for the generation of high electromagnetic (EM) fields useful for testing the susceptibilty of electronic systems to EM radiation. The techniques under comparative evaluation are: (1) reverberation; (2) T-line or coaxial; (3) mode stirred; (4) frequency stirred; (5) parallel plate T-line and (6) transverse electromagnetic mode cell. The relative strength and weaknesses of these different methods are to be established through analytical and numerical simulation techniques with the ultimate utilization medium being the anechoic chamber at Eglin AFB. Analytical characterizations provide an initial judgement framework. However, the complexity of realistic electromagnetic interation configurations dictate the complementation of such an analytical explanatory structure through a reinforcing simulation enviroment. We will use our extensive experiences in analysis and numercial computation techniques to ascertain that the analytical predictions as regards the electromagnetic field generation techniques do correlate with the particular materials and geometic details of the Eglin, AFB anechoic chamber.
