Abstract :
During last two decades we are successfully exploiting the quasioptical terahertz-subterahertz (THz-subTHz) BWO-spectrometers for spectroscopic needs (BWO - backward-wave oscillator, generator of the THz-subTHz radiation). The spectrometers allow for direct measurements of any optical characteristic of a material. In this contribution we demonstrate abilities of the THz-subTHz BWO-spectroscopy by presenting some latest results on measurements of dielectric, conducting, superconducting and magnetic materials.
