ASU Electronic Theses and Dissertations


This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries. For more information or questions about this collection contact or visit the Digital Repository ETD Library Guide or contact the ASU Graduate College at gradformat@asu.edu.


Electromagnetic band-gap (EBG) structures have noteworthy electromagnetic characteristics that include their phase variations with frequency. When combining perfect electric conductor (PEC) and EBG structures on the same ground plane, the scattering fields of the ground plane are altered because of the scattering properties of EBG structures. The scattering fields are cancelled along the principal planes because PEC and EBG structures are anti-phase at the resonant frequency. To make the scattered fields symmetrical under plane wave incidence, a square checkerboard surface is designed to form constructive and destructive interference scattering patterns to reduce the intensity of the scattered fields toward the …
