Design and implementation of plasmonic-enhanced ultra-high frequency terahertz transmitters and receivers

Terahertz spectroscopy for material imaging/sensing and characterization has received a great deal of attention over the past decade. Terahertz (THz) electromagnetic waves have frequencies in the range of 1012 Hz. Terahertz spectroscopy and imaging has many applications ranging from security, communication, food production, quality control for pharmaceutical industries, and cancer diagnosis. In the heart of every terahertz spectroscopy imaging system, there is terahertz transmitter and receiver pair antennas.
