Acoustic microscopy enables the elastic properties of materials to be imaged and measured
with the resolution of a good microscope. By using frequencies in the microwave regime, it is …

Compressional-wave velocity (VP) and quality factor (QP) have been measured in Berea
and Michigan sandstones as a function of confining pressure (P c) to 55 MPa and pore …

In response to an applied stress field or pore pressure changes, the pore space of a rock
may compact or dilate. Mechanical compaction induces the porosity to decrease, and as a …

O granito do Porto aflora em grande parte da cidade do Porto, estendendo--se ainda para
os concelhos de Vila Nova de Gaia, Matosinhos e Maia, contactando a este com o …

Patent Application is hereby incorporated by reference in its entirety as if fully restated
herein. This patent application is a continuation-in-part of US patent application Ser. No. 1 …

Scanning laser microscopy, in the confocal mode (CSLM) has been applied to a granitic
rock to characterize its fissure space. The technique provides a unique three‐dimensional …

Acoustic microscopy enables one to image the interaction of acoustic waves with the elastic
properties of a specimen with microscopic resolution. A lens with good focusing properties …

An opto-acoustic transducer assembly includes a Substrate; at least one layer of opto-
acoustic material coupled to a Surface of the substrate, where the at least one layer of opto …

We demonstrate that a scanning acoustic microscope (SAM) operating in the frequency
range 100–400MHz can detect cracks at the aggregate/paste interface and subsurface …
