Abstract

Predicting the nature of the scattering of short wavelength waves in random interconnected networks of large complicated enclosures is routinely encountered in diverse fields such as acoustics, wireless communications, and electromagnetic compatibility engineering. The Random Coupling Model (RCM), based on wave-chaos, is a statistical model describing the scattering of short wavelength electromagnetic waves in large complicated (chaotic) enclosures. The Baum-Liu-Tesche (BLT) electromagnetic topology formulation is a hierarchical framework based on the multiconductor transmission line (MTL) model for describing the flow of energy between different nodes on a network of MTL segments, originally developed to study the coupling of electromagnetic waves to aircraft cable bundles. In this research, we fuse the RCM with the BLT electromagnetic topology to create the “Statistical Topological Approach Using Wave-chaos for Electromagnetic Effects” (STUWEE) tool for predicting the statistics of the scattering of short wavelength electromagnetic waves in random interconnected networks of chaotic enclosures. In this Dissertation, I provide experimental results demonstrating the existence of wave-chaotic fluctuations in quasi-2D mode-stirred chambers (MSCs), in accordance with the RCM, and then show how these fluctuations are affected when considering random interconnections of MSCs using the BLT topology model. This work uses the BLT electromagnetic topology model to break down the networked cavities and the RCM to study statistics within each cavity. Experimental measurements have validated the fusing of the RCM with the BLT electromagnetic topology model for this application.
