They allow for direct determination of spectra of any optical parameter of a material at millimeter-submillimeter wavelengths, the domain where infrared or microwave spectrometers encounter serious methodological difficulties. We report on new technical abilities of the quasioptical BWO-spectrometers and discuss their main components. We demonstrate abilities of the THz-subTHz BWO-spectroscopy by presenting some latest results on measurements of dielectric, conducting, superconducting and magnetic materials.
