Theory, Analysis, and Applications of Multidimensional, Multiconductor Transmission-Line Metamaterials
DownloadFall 2021
The past few decades have seen incredible growth in the interest of using periodic structures to improve the efficacy of microwave-frequency devices, since they provide access to dispersion-engineered phenomena such as bandgaps, group- and phase-velocity control, and advanced resonance behaviors....

Phase Change Metamaterials for Fiber and Waveguide Integrated Compact Modulators with Built in Memory Functionality
DownloadFall 2023
Machine learning focuses on the development of algorithms and models that enable a dynamic approach to making predictions or decisions on large data-sets which cannot be readily described by analytical models. Artificial neural networks (ANN) have become the main approach to providing advance...

Theory and Applications of a Uniplanar Transmission-Line Metamaterial-Inspired Electromagnetic Bandgap Structure
DownloadFall 2015
A multitude of planar electromagnetic bandgap structures (EBGs) have been proposed for the suppression of parallel-plate waveguide (PPW) and surface-wave (SW) modes at microwave frequencies. Some of these structures have been well-modelled with transmission-line theory, however, these structures...

Design of Low-Profile Multi-Band Microwave Antennas and Components Using Metamaterial-Based Electromagnetic Bandgap Structures
DownloadSpring 2023
This thesis investigates applications of metamaterial-based electromagnetic bandgap structures, or MTM-EBGs. MTM-EBGs are uniplanar, compact, and often fully printable, making them ideal candidates for integration into planar topologies. This differs from many other metamaterial-based structures...
