Head of the Wireless Communications Research Group

Loughborough University, UK

Abstract

In this seminar, Prof. Vardaxoglou will introduce the concept and uses of MeTa-Atoms (MTAs) in electromagnetic and egineered metamaterials. MTAs are meso scale inclusions in a host material. These meta-atoms could be varied in constitution and geometry to augment a variety of artificial and novel magneto-dielectric properties. Various 3D-printed multi-layered metamaterials with different periodicities fo dielectric or metallic inclusions will be shown. The effect of the periodicity (space between adjacent elements) on the effective metamaterials properties is examined by placing the 3D-printed samples in a waveguide simulator or on a resonator measuring system. Some of these structures have already been applied in engineering applications such as antennas, microwave lenses and electronic devices.
