In this contribution we introduce the use of the UWB leaky lens antenna as an improved photo-conducting emitter for a THz time domain system. The UWB antenna presents nearly constant impedance and directive symmetric patterns over a decade of frequency bandwidth. Currently, we are working towards the fabrication of a demonstrating prototype.
Micromesh bolometers have been used in several instruments working in the submillimeter band. The bolometers are usually placed inside a waveguide and consist of a mesh absorber, at a certain distance from a back short. The mesh is made of SiNi whose thermal conductivity is tuned to the incident power and operating temperature. The impedance of the mesh is initially matched to the incoming wave impedance,...
