Resonant terahertz transmission in plasmonic arrays of subwavelength holes
Zhang, W. (EDP Sciences, 2008-07-04)A review of transmission properties of two-dimensional plasmonic structures in the terahertz regime is presented. Resonant terahertz transmission was demonstrated in arrays of subwavelength holes patterned on both metals ... -
Terahertz studies of carrier dynamics and dielectric response of n-type, freestanding epitaxial GaN
Zhang, W.; Azad, Abul K.; Grischkowsky, D. (AIP Publishing, 2003-04-28)We report the characterization of the complex conductivity and dielectric function of GaN by terahertz time-domain spectroscopy. Transmission measurements are performed on an n-type, 180-um-thick, freestanding GaN crystal. ... -
Transmission properties of terahertz pulses through an ultrathin subwavelength silicon hole array
Azad, Abul K.; Zhao, Y.; Zhang, W. (AIP Publishing, 2005-03-30)We demonstrate extraordinary THz transmission of an array of subwavelength apertures patterned on ultrathin highly doped silicon by reactive ion etching. The zero-order transmission spectra exhibit well-defined maxima and ...
