9523264 Zoughi The primary objective of this research is to investigate the relationship between the compressive strength of concrete and microwave reflection coefficient measured at the aperture of an open-ended rectangular wave guide inspecting the concrete in a contact or non-contact fashion. Subsequently, the results of this study will be used to develop a microwave, nondestructive, real-time, in-situ, cost-effective and portable sensor for estimating concrete compressive strength with a high degree of accuracy. ***

9523264 Zoughi本研究的主要目的是调查混凝土的抗压强度和微波反射系数之间的关系，在开口矩形波导的孔径处测量，以接触或非接触的方式检查混凝土。 随后，本研究的结果将被用来开发一种微波，无损，实时，原位，成本效益和便携式传感器，用于估计混凝土抗压强度具有高度的准确性。 ***
