Detection of Cracks in Concrete Structure Using Microwave Imaging Technique

Cracks in concrete or cement based materials present a great threat to any civil structures; they are very dangerous and have caused a lot of destruction and damage. Even small cracks that look insignificant can growandmay eventually lead to severe structural failure. Besides manual inspection tha...
