Nondestructive Infrastructure Measurement Using Microwave Guided-Mode Propagation and Reflection along Fiber-Reinforced Plastic Mortal Pipe Wall in Underground Pipeline

Abstract

We have proposed a new non-destructive inspection method for fiberglass-reinforced plastic mortar (FRPM) pipelines underground using microwave guidedmodes propagating along an FRPM pipe wall. In this paper, measurement results in agricultural water pipelines underground are reported.
