Design guidelines for terahertz mixers and detectors

Twin-slot antennas and coplanar waveguides are a popular choice for coupling signals to state-of-the-art mixers and detectors at terahertz frequencies. Although these sensors show promising performance in terms of noise temperature, they usually also show a considerable downward shift in the center frequency of their spectral response, especially when compared with calculations obtained with commonly used simplified models. In this paper, we...
