Abstract :
Development of dual-polarization sensitive receivers offers significant advantages for future terahertz radiometers. The key to any such system is the orthogonal mode transducer (OMT) which separates two superimposed modes into two single-mode waveguides. This letter presents the design, fabrication and measurement of a split-block asymmetrical OMT operating from 500 to 600 GHz.
