Advanced Intelligent Systems, EarlyView.A piezoelectric meta‐transducer generates an ultrasonic rainbow, steering guided elastic waves to different angles according to frequency. A dithering‐based binary electrode design enables a closer realization of the target wavenumber filter, improving directional purity and suppressing unwanted lobes. Numerical and experimental validation demonstrates

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors
Advanced Intelligent Systems, EarlyView.We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

Interactions in an Acoustic World: Dumb Hole
Advances in High Energy Physics, 2018 The present paper aims to complete an earlier paper where the acoustic world was introduced. This is accomplished by analyzing the interactions which occur between the inhomogeneities of the acoustic medium, which are induced by the acoustic vibrations ...

Advanced Physics Research, EarlyView.The impact of alloy fluctuations on the spin dynamics of mixed‐cation MAxFA1‐xPbI3 perovskite single crystals is studied experimentally by means of polarized time‐resolved photoluminescence. The high optical orientation degree, reaching 80% for x = 0.1 and 0.8, displays a minimum of 60% for x = 0.4.

Ultrasound beam steering with flattened acoustic metamaterial Luneburg lens
, 2020 We report ultrasound beam steering based on 2D and 3D flattened acoustic metamaterial Luneburg lenses at 40 kHz. The effective properties of the lenses are obtained by using the quasi-conformal transformation technique and solving the Laplace equation ...
