For enhanced or Engineered Geothermal Systems (EGS) geothermal brine is pumped to the surface via the production wells, the heat extracted to turn a turbine to generate electricity, and the spent brine re-injected via injection wells back underground

In this work, a recently developed full-wave electromagnetic analysis technique is applied to the simulation of two-dimensional finite quasi-random gratings for quantum well infrared photodetectors. This steepest descent fast multipole method is a ma

Up to 2700 terawatt-hours per year of geothermal electricity generation capacity has been shown to be available within North America, typically with wells drilled into geologically active regions of the earthâs crust where this energy is concent

Roughly 90% of the geothermal power resource in the United States is thought to reside in Enhanced Geothermal Systems (EGS). While realization of EGS development on the 100+ GWe scale would make geothermal a significant component of the renewable ene

Rough surfaces are proposed as a class of couplers for achieving high absorption in broadband quantum-well infrared photodetectors (QWIPs). The performance of these structures is predicted numerically using the steepest-descent fast-multipole method,

Intermixing of the well and barrier layers in quantum well infrared photodetectors (QWIPs) can be used to realize a broadened spectral response as well as multiple color detectors. We describe die experimental results of both rapid thermal annealing
