Session 25 overview: Mm-Wave and THz sensing

The continuing advancement of silicon electronics enables a wide range of sensing applications in mm-Wave and terahertz frequency ranges. Integrated electromagnetic interfaces support frequency-to-spatial mapping, highly confined evanescent fields, and artificial magnetic conductors to expand operating bandwidths of antennas-on-silicon. Quadrature processing and heterodyne down-conversion, both well-known from microwave communication, have been applied to passive and active imaging, respectively, to achieve record sensitivity. The session papers demonstrate advancements in imaging, spectroscopy, and near-field measurements.
