For more than last fifty years, NASA has been developing instruments primarily for space science applications in radio astronomy, planetary, and Earth sciences. In recent years, these technologies are increasingly being used in commercial applications such as high-speed communications, security imaging, autonomous landing and refueling of airplanes, and medicines. In spite of all these fascinating scientific and commercial potential, significant challenges still remain to utilize these technologies, specifically at higher frequencies such as in the terahertz range, in multiple disciplines.
Recent progress in CMOS technology as well as availability of InP HEMT based amplifiers in high frequencies has caught the imagination of researchers for developing high frequency instruments for scientific and commercial applications. Rapid progress in multiple fronts, such as commercial software for component and device modeling, low-loss waveguide circuits and interconnect technologies, silicon micromachining for highly integrated and compact packaging, and submicron scale lithographic techniques, is making it an exciting time for engineers and scientists.
In this presentation, an overview of the state of these space technologies will be presented. The talk will detail the science and other applications that specifically require technology at these high frequencies. The challenges of the future generation instruments and detectors at these frequencies in addressing the needs for critical scientific and commercial applications will also be discussed.
