Design and Fabrication of Fractal Photoconductive Terahertz Emitters and Antenna Coupled Tunnel Diode Terahertz Detectors
DownloadFall 2012
Improved terahertz (THz) photoconductive antennas that are able to both emit higher THz radiation power and detect lower THz radiation signal levels than the traditional THz photoconductive antennas are presented. Also, different classes of fractals are investigated to realize whether the...
