The power of VNA-driven quasi-optics to sense group molecular action in condensed phase systems
(Institute of Electrical and Electronics Engineers Inc., 2015-02-05)
The versatility for quasi-optical circuits, driven by modern vector network analysers, is demonstrated for the purpose of low energy (meV) coherent spectroscopy. One such example is shown applied to the curing dynamics of ...
Efficiency and spectrum evaluation of terahertz photoconductive antenna array based on GaAs substrates
(IEEE Computer Society, 2014)
Terahertz photoconductive antenna arrays with interdigitated electrodes are laid down on GaAs substrates in which different geometries are assessed for their ability to enhance performance of a time-domain spectrometer ...
Accurate determination of terahertz optical constants by vector network analyzer of Fabry-Perot response
We present a method based on a Fabry-Perot model to efficiently and accurately estimate optical constants of wafer samples in transmission-only measurements performed by a vector network analyzer (VNA). The method is ...
THz wave transmission within the metal-clad antiresonant reflecting hollow waveguides
(Optical Society of America, 2015-05-08)
We present the transmission characteristics of THz waves in the metal-clad antiresonant reflecting hollow waveguides. We have derived the equation for the blueshift of the resonance frequency. The effects of the waveguide ...
