This apparatus functions as a very-low-loss, three-port circulator.
A quasi-optical transmission line (QOTL) has been developed as a low-loss transmission line for a spaceborne cloud-observing radar instrument that operates at a nominal frequency of 94 GHz. This QOTL could also readily be redesigned for use in terrestrial millimeter- wave radar systems and millimeter-wave imaging systems.
