Abstract
This thesis addresses the electromagnetic analyses of two structures. The first structure, a low frequency loop antenna recommended for use by national standards on electromagnetic compatibility (EMC), is incorrectly specified to have the same voltage to magnetic field conversion ratio (antenna factor) when used with a 50 ohm receiver in lieu of a high impedance type ($>$600 ohm). Two independent measurement sets were performed to demonstrate the prevailing discrepancy, and a corrected antenna factor is presented for use with a 50 ohm receiver. The second structure, a partial spiral "pancake" applicator used to generate high EM fields in its vicinity, was evaluated for its (induction) reactive near-field electromagnetic characteristics. Construction of an induction zone measurement system including the development of an electrically small electric field is described. Measured data on three dimensional EM field contours over the face of the applicator, are presented.
