Terahertz Time Domain Spectroscopy (THz-TDS) is a powerful tool for investigating the electrodynamic response of any kind of material and/or metamaterial.
Using THz radiation (0.3-10 THz) one can retrieve in direct way essential information on material properties such as the refractive index and conductivity. These quantities are both described in terms of the complex dielectric function...

An improved detection scheme for a light-shining-through-wall (LSW) experiment for axion-like particle searches is introduced. Extremely intense photon fluxes (from 100 kW to 1MW) from sources at frequencies in the sub-THz range are sent in an intense magnetic field where a photon to axion-like particle conversion is possible. A single photon detector in this frequency domain based on a...
