The simulation of ultrasonic NDT of carbon-fiber-reinforced epoxy composites (CFRP) is an important challenge for the aircraft industry. In a previous article, we proposed to evaluate the field radiated into such components by means of a homogenization method coupled to the pencil model implemented in CIVA software. Following the same goals, an improvement is proposed here through the development of an original homogenization procedure based on ray theory.
