Fabrication and Analysis of 3D Asymmetric Pillar-Shaped Metamaterial for Low Terahertz (THz) Application

Artificial designed materials, known as metamaterials have changed the way we understand nature and overcome almost any limitation. Electromagnetic metamaterials exhibit high potentional for many future applications in many fields. Fabrication of 3D optical metamaterials, which would enable the use of their full potential, remains challenging due to the limitations of conventional manufacturing techniques. An approach suitable to overcome this challenge is multi-photon lithography (MPL) [1], which is a true 3D printing technique with high resolution down to sub-100 nm.
