An inverse spectral procedure was applied to reconstruct the acoustic impedance profile along the thickness direction of a plate using its thickness resonance frequencies, density and thickness. For a successful reconstruction, the material-property

In this paper there is given a method to predict ultrasonic wave velocity variations along a wave path in the through-thickness direction in a plate from thickness resonance spectra. Thickness resonance spectra are numerically calculated and two simp

We show two kinds of demonstrations using a laser ultrasonic method. First, we present the results of Young's modulus of ceramics at temperatures above 1600 °C. Second, we introduce the method to determine the internal temperature distribution of a

Severe vortex bending as large as 90\ifmmode^\circ\else\textdegree\fi{} and giant avalanche were observed over a large area of a disk-shaped type-II superconductor in the mixed state using a contactless ultrasonic technique. This phenomenon is greatl

We have developed an on-line system for the measurement of plastic strain ratio of steel sheet using a thickness resonance EMAT that measures the thickness resonance frequencies of three different modes of bulk ultrasonic waves. The effective size of

Using Bragg ionization curves, measurements of the average stopping power of organic polymers relative to that of water have been made for 70 MeV protons losing about 30 MeV in the absorbers. By comparing calculated curves to experimental ones, I‐v
