Analysis of the Air Force Weapons Laboratory's horizontally polarized dipole electromagnetic pulse simulator

This report presents an analysis of the operating characteristics of the Horizontally Polarized Dipole Electromagnetic Pulse Simulator located at Kirtland Air Force Base, New Mexico. The analysis and an attendant computer program resulting from this work enable operators of the HPD Simulator to compute with reasonable accuracy and efficiency the transient electromagnetic field radiated by the simulator into a specified test volume. A theory is developed for the loaded loop radiator, which is constructed from cages of loaded wires, and coupled, integro-differential equations are formulated for the unknown current on the wires of the structure. These equations are solved in the frequency domain and desired radiated fields are computed via Fourier transform techniques.
