Composite materials are increasingly used in the aerospace industry. To fully realise the
weight saving potential along with superior mechanical properties that composites offer in …

Time reversal (TR) signal processing is an effective tool to exploit a reverberant environment
for the intentional focusing of airborne, audible sound. A previous room acoustics TR study …

This paper deals with the time reversal approach along with signal classification using ϕ-
divergences in biomedical applications for localization and statistical classification of …

Time reversal (TR) focusing of airborne ultrasound in a room is demonstrated. Various
methods are employed to increase the amplitude of the focus. These methods include …

An equivalent circuit model has been developed to model a one-dimensional waveguide
with many side-branch Helmholtz resonators. This waveguide constitutes a phononic crystal …

The Time Reversed Elastic Nonlinearity Diagnostic (TREND) has a long history of
successful nondestructive detection of cracks in solids using nonlinear indicators. Recent …

This article reports the results of an experiment (N= 10) that employs continuous auditory
feedback to influence participants' routing choices while walking between two points by …

Time reversal focusing above an array of resonators creates subwavelength–sized features
when compared to wavelengths in free space. Previous work has shown the ability to focus …

In acoustics, time-reversal processing is commonly used to exploit multiple scatterings in
reverberant environments to focus sound to a specific location. Recently, the nonlinear …

Time Reversal (TR) is a technique that may be used to focus an acoustic signal at a
particular point in space. The effect of transducer placement within a room as well as the …
