Air-Coupled and Resonant Pulse-Echo Ultrasonic Technique
Sensors, 2019 An ultrasonic, resonant, pulse-echo, and air-coupled nondestructive testing (NDT) technique is presented. It is intended for components, with regular geometries where it is possible to excite resonant modes, made of materials that have a high acoustic ...

Numerical Analysis of Microwave NDT Applied to Piping Inspection
MATERIALS TRANSACTIONS, 2012 Numerical simulations using finite element software were carried out to discuss the physical background of nondestructive inspections of pipes using microwaves. The simulations were conducted using an axisymmetric configuration modeling pipe with wall thinning to evaluate the effect of the profile of the wall thinning on the microwave propagation. Both
