Prediction of the mechanical properties of wood using guided wave propagation and machine learning
Construction and Building Materials, 2020Accurate nondestructive prediction of the mechanical properties of wood is a critical quality control task for timber grading. Currently, the ultrasonic wave method is widely used for this purpose, which overestimates the static mechanical properties of ...

Magnetohydrodynamic Waves in Wave Guides
The Physics of Fluids, 1959Propagation of magnetohydrodynamic waves is investigated in a fluid bounded by a cylindrical surface of constant, but not necessarily circular, cross section. The fluid is assumed to be nonviscous and perfectly conducting with a constant magnetic field applied parallel to the walls of the cylinder.

Ultrasonic guided wave monitoring of an operational rail track
, 2020An experimental monitoring system was installed on an operational heavy haul rail track. The system used two piezoelectric transducers mounted under the head of the rail to transmit and receive ultrasonic guided waves in pulse-echo mode and data were ...

Holographic-Based Leaky-Wave Structures: Transformation of Guided Waves to Leaky Waves
IEEE Microwave Magazine, 2021The term space wave refers to a wave that is propagating through an open medium with a diverging wavefront as it moves away from the source. The term guided wave denotes a variety of wave configurations that are being carried by a closed/open/partially ...
