DESCRIPTION:Passive electromagnetic devices such as transmission lines\, fi
 lters\, and antennas are essential parts of a wireless system. They often 
 dominate the system’s efficiency\, bandwidth and noise performance. Trad
 itional passives often operate in a time-invariant manner as they are buil
 t with materials and structures that have time-independent properties. The
 y are subject to many well-known fundamental limits such as the reciprocit
 y of the transmission line\, limit of quality factors of passive filters\,
  and limit of efficiency bandwidth products. The utilization of transistor
 -based active electronics may help to overcome some of these challenges bu
 t they oftentimes incur noise and power handling issues. Transmission line
 s\, with time-varying impedances\, can help to overcome many of those trad
 itional limits in passives while offering a better noise and power handlin
 g performance compared to the active transistor-based circuits.\n\nIn this
  talk\, multiple initiatives supported by NSF and DARPA will be reported o
 n the development of a new class of electromagnetic devices based on time-
 varying transmission lines. These devices include circulators\, mixers\, f
 ilters\, and correlators that may be constructed on integrated semiconduct
 or platforms with time-dependent property enforced through parametric modu
 lation or dynamic switching. Potential new applications such a full-duplex
  radios\, tunable RF front-ends may be developed with this novel device co

 ansmission lines\, filters\, and antennas are essential parts of a wireles
 s system. They often dominate the system&amp;rsquo\;s efficiency\, bandwidth a
 nd noise performance. Traditional passives often operate in a time-invaria
 nt manner as they are built with materials and structures that have time-i
 ndependent properties. They are subject to many well-known fundamental lim
 its such as the reciprocity of the transmission line\, limit of quality fa
 ctors of passive filters\, and limit of efficiency bandwidth products. The
  utilization of transistor-based active electronics may help to overcome s
 ome of these challenges but they oftentimes incur noise and power handling
  issues. Transmission lines\, with time-varying impedances\, can help to o
 vercome many of those traditional limits in passives while offering a bett
 er noise and power handling performance compared to the active transistor-
