DESCRIPTION:Silicon-based Terahertz systems is a field that is only about a
  decade old. In this time\, we have seen a phenomenal growth of silicon sy
 stems operating at THz frequencies for a wide range of applications in sen
 sing\, imaging and communication. It can be argued that both the ‘THz ga
 p’ and the ‘technology and applications gap’ is closing in meaningfu
 l ways in the THz range. Technologies beyond 100 GHz focusing on sensing\,
  imaging and wireless back-haul links are getting attractive as we enter i
 nto a new area of highly dense network of autonomous systems requiring ult
 ra-high speed and reliable links.\n\nIn order to move beyond this inflecti
 on point as Moore’s law continue to slow\, I will discuss why we need to
  look beyond the classical ‘device’-level metrics of efficiency and se
 nsitivity of THz sources and detectors towards holistic ‘system’ level
  properties such as scalability and programmability. Such properties are c
 ritically important for applications in sensing and imaging\, as evidenced
  across sensor fusion technologies across mmWave\, IR and optical frequenc
 ies. The ultimate programmability in THz sources and sensors is one that c
 an synthesize or receive THz fields with arbitrary configuration and spect
 rum. In this talk\, I will highlight approaches that cut across electromag
 netics\, circuits\, systems and signal processing\, to allow for such reco
 nfigurability in THz signal synthesis and sensing\, yet realized with devi
 ces that are themselves not very efficient. Particularly\, we will demonst
 rate approaches to THz CMOS sensors reconfigurable across the three field 
 properties of spectrum (100 GHz-1000 GHz)\, beam pattern and polarization\
 , programmable THz metasurfaces with CMOS tiling\, and enabling dynamic sp
 ectrum shaping and physically secure sub-THz links. In the end\, I will co
 mment on what could be the major directions for the field in the coming de
 cade.\n\nSpeaker(s): Prof. Kaushik Sengupta\, \n\nVirtual: https://events.
