A New Class of Resonant Metasurfaces Based on Highly Subwavelength Metamaterial-Lined Apertures and Metamaterial-Coated Discs
DownloadSpring 2019
This work presents analytical, numerical and experimental studies of a new class of resonant metasurfaces (MTSs), which may also be classified as miniaturized-element frequency selective surfaces (FSSs). The proposed MTS unit cells consist of circular aperture or disc resonators that are made...

Continuum Modelling and Analysis of a Class of One and Two Dimensional Elastic Metamaterials with Local Rotation
DownloadFall 2022
The group of materials classified as "metamaterials" have accrued great interest in the scientific community as of late for their potential to revolutionize several multidisciplinary applications. Metamaterials are defined as synthetic/man-made materials which have been engineered to possess a...
