Electricity as a form of energy is not exactly efficient because much of it is lost as heat. Or as University of Utah electrical and computer engineering associate professor Mike Scarpulla says: “Heat is the universe’s garbage can for energy.” Inside power systems, converters and electronic switches convert and control electrical energy from one form […]

University of Utah mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory, called “field patterns,” published today in Proceedings of the Royal Society A. Field patterns are characteristic patterns of how disturbances react to changing conditions. Because field […]
