 S\, liquid crystals\, and ferrite materials have long been used as high-fr
 equency tuning elements\, but they face fundamental limitations in tuning 
 range\, power handling\, and miniaturization—critical challenges for nex
 t-generation RF systems. Cold plasmas offer a disruptive alternative: by p
 recisely controlling internal plasma parameters such as electron density\,
  their dielectric permittivity and conductivity can be unprecedently tuned
 \, enabling novel\, reconfigurable electronic and RF devices with extreme 
 reconfigurability. Beyond RF tuning and radiation\, cold plasmas have also
  emerged as an enabling technology in many other fields\, including medica
 l treatments\, semiconductor fabrication\, electric propulsion\, particle 
 acceleration\, water decontamination\, material processing\, and PFAS remo
 val. However\, generating stable plasmas is not trivial due to the need fo
 r energy-hungry sources. Microwave resonators provide a breakthrough solut
 ion by efficiently storing and amplifying electromagnetic energy\, enablin
 g energy-efficient plasma generation at power levels as low as milliwatts.
  These plasmas exhibit superior properties\, including higher ionization a
 nd dissociation rates\, enhanced electron density\, and greater production
  of reactive species while maintaining low temperatures. In this talk\, I 
 will review our advances in electromagnetic-plasma interactions\, with a f
 ocus on high-power microwaves and energy-efficient microwave plasma source
 s\, highlighting key applications.\n\nBio: Abbas Semnani is an Associate P
 rofessor of Electrical Engineering and the Director of the Adaptive Radiof
 requency and Plasma Lab (ARPL) at the University of Toledo. Before joining
  UToledo in 2019\, he spent seven years at Purdue University\, where he fo
 cused on micro-discharges in high-frequency micro/nanoelectronics. His res
 earch interests include high-power microwaves\, tunable and compact antenn
 as\, reconfigurable RF electronics\, and microwave plasma sources for vari
 ous applications. Dr. Semnani received the 2019 IEEE &#39;Tatsuo Itoh&#39; Award\,
  the NASA Glenn Faculty Fellowship in 2022\, and the NSF CAREER Award in 2
 024. His research has been supported by NSF\, DOE\, ONR\, ARL\, NSWC Crane
