A sub-Terahertz circular dichroism spectrometer is developed and built based on a vector network analyzer driven quasi-optical system at 220–325 GHz sub-THz frequency domain (VNA-CD). The main goal is to explore the potentially significant absorption features in THz signatures of aqueous protein samples.
