DESCRIPTION:Abstract: Millimeter‑wave (mm‑wave) drilling is an emergin
 g thermal rock‑removal technology with the potential to transform access
  to superhot geothermal resources beyond the reach of conventional mechani
 cal drilling. By delivering electromagnetic energy directly to the rock fa
 ce\, mm‑wave irradiation induces rapid heating\, thermal stress generati
 on\, and material removal through a combination of cracking\, spallation\,
  and melting. However\, the efficiency and controllability of the process 
 depend sensitively on rock composition\, microstructure\, confinement\, an
 d operating conditions.\nIn this talk\, I will present recent advances in 
 the modelling and experimental investigation of millimetre‑wave drilling
 . I will first provide an overview of the key mechanisms involved and expl
 ain how the process has been studied both experimentally and theoretically
 . Finally\, I will outline our ongoing efforts to deploy this technology i
 n the field\, summarize our progress to date\, and describe the upcoming t
 ests.
