Nondestructive Electromagnetic Characterization of Perfect Electric Conductor Backed Uniaxial Materials

Abstract

First, this dissertation presents motivation and background on complex media and their characterization. Next, a scalar-potential formulation is presented to derive Green functions describing a parallel plate region containing two layers of uniaxial material. Two measurement techniques based on those Green functions are then developed and analyzed via uncertainty analysis. One technique is validated using laboratory measurements compared to those from a mature destructive technique. Next, the advantages and disadvantages of both proposed techniques are discussed as well as suggested areas of promising future research. Ultimately, this work demonstrates that nondestructive characterization of conductor-backed uniaxial materials is not only possible, but can be achieved in an efficient, practical manner with results on par with mature destructive techniques.
