First demonstrated millimeter-wave identification (mmID) assembly of two cascaded biconvex lenses backed by an array of individual backscattering elements (pixels).

28 GHz

Cascaded PTFE multi-lens system significantly broadens angular coverage 204% over a single lens design.

Dense IoT swarms of solar-powered, 5G-connected mmID devices in digital twinning “smart” cities and “smart” agriculture applications.

-15.7 dBsm peak differential radar cross section (RCS) with a ±50° -10 dB beamwidth, or 2,244 sr about boresight. 82.5 m range within 6 cm of true range demonstrated with FMCW radar interrogator at 0° and 50° incident angle (best- and worst-case interrogation within the -10dB angular beamwidth).
