Control of terahertz polarization-sensitive filters based on the formation by a magnetic field of structures of microparticles of the 5BDSR alloy in a liquid medium
This work presents the results of the development of a version of a polarization-sensitive magnetic-field-controlled bandpass filter in the range from 0.2 to 1.5 THz. The filter is based on a magnetic fluid created by the authors, consisting of 5BDSR alloy microparticles up to 50 microns in size and 5W40 synthetic motor oil for automobiles. It was also shown that by controlling the behavior of microparticles in a magnetic fluid using an external magnetic field, one can create an analogue of diffraction gratings.
