Sandwiched between the infrared and microwave parts of the electro-magnetic spectrum lies the terahertz window — a valuable and largely untapped portion of energy that can reveal a huge variety of unknowns, from hidden weapons and suspicious foreign objects to the thickness of paint and quality of medicine … According to Seongsin “Margaret” Kim, associate professor of electrical and computer engineering at the University of Alabama, terahertz technology has the potential to revolutionize the future and open new opportunities that will benefit society. “Our community needs to be more patient than ever and focus on exciting science that can lead to this revolution coming in the near future,” she said.
