  Dr. Hesler’s research has focused on developing terahertz components and systems, including THz Vector Network Analyzer Extenders, wideband receivers for passive remote sensing, detectors with wide demodulation bandwidth for communications applications, and state-of-the-art frequency multipliers and mixers. Two specific examples of his efforts are:- The development of state-of-the-art THz Vector Network Analyzer Extenders and waveguide calibration techniques that have enabled the first ever fully calibrated measurements in the 500-1500 GHz range, including on-wafer TRL calibrations to 1.03 THz. These THz extenders are being used at leading research institutions around the world including JPL, NGC, Fraunhofer, IHP, NIST, Chalmers and NICT.- The invention of a new, broadband frequency tripler design that has yielded exceptional broadband (tunerless) performance and is remarkably easy to fabricate in large volume. This new design is now an enabling component in the local oscillator systems of Atacama Large Millimeter Wave Array; a large (~$2B) international project that built an array of 66 astronomical antennas for the frequency range 100-1000 GHz.Terahertz systems based on Dr. Hesler’s innovative designs are now used in hundreds of research laboratories throughout the U.S., Europe, Asia and the Middle East. These often unique systems are enabling ground-breaking scientific measurements in diverse fields such as astronomy, chemical spectroscopy, plasma and accelerator diagnostics, communications, weather and environmental monitoring, imaging, antenna test ranges, and Terahertz radar characterization.
