Abstract :
We present a scheme for achieving active composite right/left handed (CRLH) transmission line metamaterial waveguides in the THz by loading THz QC-laser metal-metal waveguides with sub-wavelength capacitive and inductive structures. We discuss our progress in using transmission-line metamaterial concepts for the engineering of THz active leaky-wave antennas that provide amplification and exhibit beam steering.
