Fabrication of a Metasurface “Mirror” Using Multiphoton Lithography for THz Applications

Inspired by nature's elements, metamaterials have gained significant attention in the field of photonics<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup>, and not only. Given a specific architecture to the meta-atoms we are able to manipulate the electromagnetic waves<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and create novel applications overcoming the challenges where most of natural elements are not suitable to be used. An interesting region of frequencies like this, is the low THz (0.1-5 THz) regime where most of natural elements lack of electromagnetic response. This results to limited applications and devices, that can be potentially used between the electronics and photonics field.
