Study on Active Terahertz Metamaterials
Abstract
In this program the grantee investigated THz radiation sources and modulators formed by active metamaterials made with the grantee's original interdigitated grating gate (DGG) structures on HEMT device layers. The principle of operation is the two-dimensional plasmons which are confined into artificial dimensions of metamaterial structure in a HEMT and are electrically or optoelectronically excited to seed the electromagnetic radiation.
