Abstract
The high-frequency behavior of generalized ray arrivals is discussed with a view towards material characterization by means of measurements of the dispersion of ultrasonic pulses. The effect of beam spreading is treated exactly. Signal processing algorithms are developed. They are demonstrated with a synthetic signal obtained in an elastic material.Keywords
