In vivo terahertz (THz) imaging of human skin needs to be done in reflection geometry due to the high attenuation of THz light by water in the skin. To aid the measurement procedure, there is typically an imaging window onto which the patient places the area of interest. The window enables better pulse alignment and helps keep the patient correctly positioned during the measurement. In this paper,...
We have developed a novel wire grid polarizer on a thin film substrate to overcome multiple reflection issues found in conventional polarizers. In this paper, we show how our polarizer can be used to characterize the vertical and horizontal polarization components of a THz photoconducting antenna.
The low-cost fabrication of a metal wire-grid polarizer for the terahertz (THz) region was demonstrated. An aluminium grid was patterned onto a thin silica (SiO2) layer. The performance of the THz polarizer was evaluated through experimental measurements. The experimental results were compared with the simulation results.
The catalytic dehydrogenation (DH) and oxidative dehydrogenation (ODH) of light alkanes are of significant industrial importance. In this work both carbonaceous material deposited on VO x /Al 2 O 3 catalysts during reaction and unsupported carbon nanofibres (CNFs) are shown to be active for the dehydrogenation of butane in the absence of gas-phase oxygen. Their activity in...
