Back reflection of ultrasonic waves from a liquid-solid interrace
A new acoustic phenomenon has recently been observed in experiments where a bounded beam of ultrasound is incident upon a smooth liquid-solid interface. A significant amount of coherent radiation is found to be backscattered in the general direction of incidence. The angle of back reflection is observed to be equal to the Critical Rayleigh angle or leaky wave angle. Most of these observations w...
متن کاملAmplification of waves during reflection from a rotating ublack hole
The effect whereby waves are amplified during reflection from a rotating "black hole" is investigated. This process is connected with the extraction of energy and momentum from a "black hole." The conditions for the existence of the effect are found. The amplification factor is computed for the model case of scalar waves. For waves with frequencies which do not satisfy the conditions for the ex...
متن کاملUltrasonic reflection and material evaluation
2014 An overview is given describing the physical basis of ultrasonic reflectivity as it relates to solid material characterization. The examples given illustrate critical angle reflection, Rayleigh and Lamb waves, and crystal orientation via reflection measurements. Revue Phys. Appl. 20 (1985) 377-381 JUIN 1985, PAGE Classification Physics Abstracts 43.20
متن کاملMouth State Detection From Low-Frequency Ultrasonic Reflection
This paper develops, simulates and experimentally evaluates a novel method based on non-contact low frequency ultrasound which can determine, from airborne reflection, whether the lips of a subject are open or closed. The method is capable of accurately distinguishing between open and closed lip states through the use of a low complexity detection algorithm, and is highly robust to interfering ...
متن کاملNonreciprocal reflection of a subwavelength hole array.
We present measurements of the wavelength-dependent reflectivity of a subwavelength metal hole array on a glass substrate. We compare the observed resonant structures with those found in transmission and note a nonreciprocity under illumination from the air versus the glass side. This can be used to verify on which interface the surface plasmons are resonantly excited and to estimate the losses...
