Abstract

In this paper, some of our recent works on the design of different types of nanostructured surfaces, the terahertz generation, terahertz lenses, and terahertz metamaterials are reviewed and discussed. The mechanism behind the terahertz radiation is the photoelectric emission effect, which leads to the oscillating motions of emitted electrons and are affected by the electric field inside the metal. Furthermore, by using those nanostructured surfaces, terahertz lenses, which are due to the excitation of surface plasmons, and terahertz metamaterials, which results from the effective inductor-capacitor resonator, are also presented.
