Abstract
The theme of microwave heating for thermographic nondestructive evalua tion has been addressed experimentally. Slabs and sandwiches, made of Kevlar or fiberglass, containing artificial defects were heated by mea ns of cavity applicators fed by 2.45 GHz high microwave power (600-1,7 00 W). The results, compared with that obtained using X-my, ultrasound , and infrared excited thermography, showed the effectiveness of this technique. Some simple theoretical modelling has been also developed.
