Thz Meta-Foils: A Platform For Practical Applications Of Metamaterials

Abstract

THz meta-foils are a three-dimensional all-metal left-handed metamaterial operating at THz frequencies. In this thesis, we design, manufacture and demonstrate four new THz meta-foils with various interesting functions. Functional multi-band THz meta-foils, crossed meta-foils, conjugated rosette chiral meta-foils and broadband chiral meta-foils are numerically and experimentally investigated, respectively. All THz meta-foils proposed here provide a versatile and practical platform for developing THz materials and devices with the strong resonance properties and the tunable features.
