A conflict exists in ultrasonic measurements between the resolution which requires higher frequency, and the penetration depth which requires long wavelength. Traditional pulse-echo method for elastic property measurements fails when the sample becomes too thin to allow the separation of repeated echoes. A data processing technique is described here which may provide a solution to this conflict. Elastic properties were successfully measured in samples as thin as 5% of the wavelength λ.
