1. Introduction. Ultrasonic non-destructive testing techniques (NDT) based on application of guided waves are already used for inspection of plate - type structures made of various materials including composite materials. Applicability of such methods may be widened by employing air-coupled techniques (1). The main currently encountered problem is big losses of ultrasonic signals caused by the attenuation and significant mismatch of acoustic impedances of ultrasonic transducers and air. The objective of this work is to develop novel air-coupled ultrasonic techniques based on excitation of guided waves by means of improved ultrasonic arrays and to apply them for a non-destructive evaluation of the properties of sheet type composite and polymeric structures.
