In two recently published articles, researchers Kaushik Sengupta (left), an assistant professor of electrical engineering, and Xue Wu (right), a Princeton graduate student in computer science, describe one microchip that can generate terahertz waves, and a second chip that can capture and read intricate details of these waves. Terahertz waves sit between the microwave and infrared light wavebands on the electromagnetic spectrum and have unique characteristics, such as the ability to pass through most non-conducting material such as clothing or boxes without damaging human tissue or DNA.
