A truly rigorous and quantitative approach to Black Body radiation is the fundamental starting point of experimental Radiometry in the region of Far Infrared and Millimeter waves (FIR). Absolute (i.e. calibrated) measurements of electromagnetic radiation are widely used in many areas of Physics, from Plasma Diagnostics in Nuclear Fusion, to Radio Astronomy and Atmospheric Physics. Along the years...
The 0.1–30 THz frequency range routinely studied with time-domain spectroscopy (TDS), has an unquestionable diagnostic potential for tokamak plasmas, thus THz-TDS applications appear to be the natural evolution of FIR and submillimeter wave diagnostics. By illuminating the plasma with a THz beam, phase, intensity and polarization of reflected and transmitted wave can be simultaneously detected, potentially...
We discuss an extensive set of experimental results about the spectroscopic properties of different materials in THz spectral range, as part of the development of a THz-based Plasma Diagnostic for Nuclear Fusion Applications.
