An electrical engineer at Missouri University of Science and Technology is using microwave energy to test concrete and rehabilitated aluminum, and in the future her work could lead to safer bridges and aircraft parts.
Dr. Kristen Donnell, an assistant professor of electrical and computer engineering at Missouri S&T, studies those materials using an active microwave thermograph (AMT) that highlights flaws that could compromise safety or effectiveness. It works by using microwave energy to heat a defined section of material, which is looked at using infrared thermography imaging. It’s a method of nondestructive testing (NDT) that is fairly undeveloped, Donnell said, but it’s being pioneered at Missouri S&T. [Read more…]
