Reflection and transmission coefficient approximation at weak-contrast interfaces for strong VTI media
《Science China Earth Sciences》2024年第12期3914-3938,共25页Xingyao YIN Yaming YANG Kai LIANG Kun LI 
supported by the National Natural Science Foundation of China(Grant Nos.42030103,42274157,41974119);the Marine S&T Fund of Shandong Province for Pilot National Laboratory for Marine Science and Technology(Grant No.2021QNLM020001-6);the Natural Science Foundation of Shangdong Province(Grant No.ZR2022MD092)。
Reflection and transmission(R/T)responses characterize the propagation and energy distribution of incident and reflected waves on both sides of an interface which is crucial for imaging,amplitude variation with offset...

Thickness Determination for a Two-Layered Composite of a Film and a Plate by Low-Frequency Ultrasound被引量:9
《Chinese Physics Letters》2007年第3期755-758,共4页毛捷 李明轩 王小民 
Supported by the National Natural Science Foundation of China under Grant Nos 10474113 and 10234060.
We present an ultrasonic method for determining the thickness of a composite consisting of a soft thin film attached to a hard plate substrate, by resonance spectra in the low frequency region, The interrogating waves...
