Randall.Daniliuc, Joshua D.2013-09-242017-04-072013-09-242017-04-072013-082013-09-24http://hdl.handle.net/2104/8823Previously, a novel microwave measurement device known as the Guided Microwave Spectrometry (GMS) system was developed for retrieving properties of material under test (MUT) and non-destructively measuring the composition of various mixtures of known constituents. In this work, simulation and measurement studies on this GMS technology are presented to investigate how electromagnetic waves propagate in the structure. I will explain the wave propagation characteristics and how each individual component of the GMS contributes to the overall system response. The GMS system responses to both homogeneous and inhomogeneous materials inside the chamber are examined as well. Finally, I present ways to enhance GMS system performance by carrying out comprehensive parametric studies on both rectangular and circular GMS systems.en-USBaylor University theses are protected by copyright.
