This article deals with ultrasonic transmission through multilayer systems. The equivalent
ultrasonic impedance of such systems is based on the transmission line built as a …

This paper presents an inverse methodology with the aim to characterize a layered material
through the identification of acoustical and mechanical properties of its layers. The …

To optimize the ultrasonic transducer parameters and to interpret the measured results,
knowledge about the sound field is required. In ultrasonic testing, the transducer generated …

In ultrasonic measurement situations, when dealing with media of multi-layered structures
consisting of 1 or more thin layers, analysis of the measured ultrasonic waveform can be …

As to optimize the ultrasonic transducer parameters and to interpret the measured results,
knowledge about the sound field is required. That is relevant both in the fields of non …

This paper presents a computational method to calculate the reflected and transmitted
ultrasonic fields at interfaces of complex geometry. The method is performed in two steps. As …

The aim of this work is to model the behavior of ultrasonic waves into multi‐layered
components. The propagation of the direct field transmitted through the inner interfaces is …

Based on a simple second‐order thin layer asymptotic expansion for the transfer matrix, an
explicit asymptotic solution for the stiffness matrix for a generally anisotropic piezoelectric …

The surface impedance matrices in stratified plates made of fluid layers and/or anisotropic
absorbing solid layers link the particle velocity field to the stress field at any interface. A …

The aim of this work is an experimental validation of the reflected and transmitted fields
through a viscoelastic material when a bounded ultrasonic beam is incident at different …
