Abstract : This investigation determined the electromagnetic (EM) wave characteristics of an electromagnetic pulse (EMP) simulator from 6 MHz to 30 MHz, and determined a method of reducing unwanted wave reflections within the simulator. The electromagnetic fields produced by the EMP simulator were determined by using a method of moments routine for both a perfectly conducting ground plane and a concrete ground plane. The electromagnetic wave absorber was analyzed using two-port network theory. Data for the absorption characteristics of a wire model used within the EMP simulator was accomplished using a method of moments approach. Determination of the electromagnetic wave reflections on the wire was assessed. A determination of the optimal placement of the absorber material within the EMP simulator is made. (Theses).
