Title: 3D Printing of Metamaterials with Conductive Elements
Author: Tuttle, Geoffrey
Date Created: 2016
Description: To fulfill their engineered purpose, resonant metamaterials require arrays of complex three-dimensional geometries composed of non-conductive dielectrics and highly conductive materials. In order to create these geometries, 3D printers must be abl...

Title: ADDITIVE MANUFACTURABLE METASURFACES FOR RF APPLICATION
Author: Hecht, Kristy
Date Created: 2020
Description: Materials found in nature exhibit behaviors with certain properties such as mass density, permeability, and permittivity. Unfortunately, there are limitations and restrictions to the behaviors of these materials that can be overcome with the use o...

Title: Application of Local Transmission Line Modelled Metasurfaces and Comparison to Huygens-Fresnel Principle Modelled Metasurfaces
Author: Trusnovic, Matthew
Date Created: 2021
Description: Metasurfaces have many applications, from beam steering effects to polarization control. There are two main theories that are used in the creation of modern metasurfaces, one based on the Huygens-Fresnel Principle and one based on Local Transmissi...

Title: DESIGN AND FABRICATION OF LOW LOSS AND LOW INDEX OPTICAL METAMATERIALS
Author: Cox, Princess
Date Created: 2013
Description: The study of optics has changed over the past 3000 years. We have developed beyond the early lens technologies of quartz and other types of glass materials and new materials are being engineered to enhance the properties of naturally occurring mat...

Title: Electromagnetic Wave Phenomena In Periodic Metastructures
Author: Schenk, John
Date Created: 2010
Description: There is an active effort toward the development of negative index metamaterials for application in high-resolution imaging. In particular, engineering an artificial material exhibiting an index of exactly -1, may permit sub-wavelength imaging. Th...
