Experimental verification of PEEC based electric field simulations

Abstract [en]

This paper describes how to model a electronic three-dimensional structure and its electromagnetic part with circuit variables instead of field variables as for commercial EM field solvers. The equivalent model is developed from an electric field integral equation and is applicable in the time and the frequency domain. The purpose with this master thesis is to evaluate the partial element equivalent circuit (PEEC) formulation with the circuit simulation program PSpice to characterize microwave circuits. For a constructed prototype the electric far field emitted should be computed using the PEEC model in PSpice and then verified with corresponding measurements. The PEEC theory was collected from various articles written by Ph. D. Albert E. Ruehli who has a large experience on the subject. A printed circuit board was manufactured and the corresponding PEEC model developed. Two different tests were performed to evaluate the PSpice simulations of the equivalent circuit. In the first test the input impedance of the test circuit was modeled with very good accuracy. In the second test the electrical far field emitted was calculated from the PSpice simulations. This was also done with good accuracy, but the results should be verified with a full wave EM solver since all field measurements are susceptible to noise interactions.
