The elastic-wave scattering at interfaces, such as cracks, is essential for nondestructive
inspections, and hence, understanding the phenomenon is crucial. However, the elastic …

The ultrasonic C-scan method is a well-known non-destructive inspection method which
typically analyzes ultrasound echoes in time domain. Although demonstrated for a variety of …

This study investigates the use of both amplitude and time-of-flight based pulsed ultrasonic
polar scan (P-UPS) as a sophisticated non-destructive damage sensor for fiber reinforced …

Already in the early 1980's, it has been conjectured that the pulsed ultrasonic polar scan (P-
UPS) provides a unique fingerprint of the underlying mechanical elasticity tensor at the …

In this paper, the hybrid compliance-stiffness matrix method for simulating wave propagation
in (delaminated) multilayered media with viscoelastic anisotropy has been confronted with …

Ultrasound is used extensively in medical imaging and therapy, non‐destructive testing, flow
sensing, underwater range assessment, and acoustic microscopy. To ensure the accuracy of …

In the early 1980's, the ultrasonic polar scan (UPS) technique was developed to assess the
fiber direction of composites in a nondestructive way. In spite of the recognition by several …

Efficiently detecting the state of charge (SOC) of lithium-ion battery is crucial for advancing
new energy technologies, and using ultrasound for SOC characterization has been …

ABSTRACT A slot microring resonator acoustic sensor (MRAS) using the PDMS package
was proposed to achieve ultra-high sensitivity acoustic detection. The acoustic detection …

The ultrasonic polar scan (UPS), either in transmission, reflection or backscatter mode, is a
promising non-destructive testing technique for the characterization of composites, providing …
