title: Modeling of propagation and echo formation in a multilayered structure
abstract: In the aim of simulating the ultrasonic inspection of multilayered structure, we propose a hybrid model, based on transfer matrices and ray tracing formalisms. This approach allows one to predict the response of structures containing defects of finite size such as delaminations or adhesion defect.
