Imaging flaws close to surface using focused surface acoustic waves
(IEEE, 1986-11)The resolving power and detection ability of the focused surface acoustic wave (SAW) imaging modality is investigated in this paper. In this mode of imaging, conical bulk acoustic waves are used to generate and focus leaky ... -
A new surface acoustic wave imaging technique
(Springer, Boston, MA, 1986-07)A new type of imaging technique is presented which incorporates focussed surface acoustic waves. Surface acoustic waves are generated on the surface to be imaged by use of conical wavefronts. The conical wavefronts are ... -
Penetration depth of the scanning acoustic microscope
(IEEE, 1985-03)A definition for the penetration depth of the scanning reflection acoustic microscope is given. With this definition it is possible to calculate the penetration depth of a given lens geometry for a given material. The ... -
Response of surface acoustic wave imaging systems to cylindrical inhomogeneities
(IEEE, 1988-10)The authors present a theory to predict the response of a SAW (surface acoustic wave) imaging system. In particular, they calculate the response to cylindrical cavities as a function of cavity position with respect to the ... -
Tailoring vibrational signature and functionality of 2d-ordered linear-chain carbon-based nanocarriers for predictive performance enhancement of high-end energetic materials
(MDPI, 2022-04-01)A recently proposed, game-changing transformative energetics concept based on predictive synthesis and preprocessing at the nanoscale is considered as a pathway towards the development of the next generation of high-end ... -
Use of a conical axicon as a surface acoustic wave focusing device
(IEEE, 1987-01)Ultrasonic axicons generate waves which focus on a line. They are used in various imaging applications as hulk wave focusing devices with a very long depth of focus. A new type of conical axicon is introduced. It consists ... -
V(Z) of the surface acoustic wave focusing system
(IEEE, 1986-11)It is possible to define a V(Z) function for the surface acoustic wave (SAW) focusing system for a class of reflectors similar to that defined in acoustic microscopy. In this case V(Z) is a function which relates the ...
