Abstract
Every object has the ability to radiate and scatter electromagnetic waves. The ability to predict frequencies of maximum radiation or scattering has been limited to simple objects, such as dipoles, or objects with high degrees of symmetry. This thesis describes modifications that can be made to a computational electromagnetic technique, the Method of Moments, to allow for such. predictions to be made for complex metallic objects. This new technique has been implemented as a MATLAB computer program and tested on objects with known resonance frequencies. Finally, the code's ability to handle large complex objects is demonstrated by investigating the resonance frequencies for a Cessna aircraft
