Irreversible magnetization switching using surface acoustic waves
, 2013 An analytical and numerical approach is developped to pinpoint the optimal experimental conditions to irreversibly switch magnetization using surface acoustic waves (SAWs). The layers are magnetized perpendicular to the plane and two switching mechanisms

Understanding the Effects of Conductive Polymer Electrode Coating on Recorded Neural Signals
Advanced Healthcare Materials, EarlyView.Conductive polymer coatings are widely explored to improve the quality of signals recorded with chronically implanted neural electrodes, offering enhanced biocompatibility along with reduced electrode impedance. Combining computational modelling and data from PEDOT:PTS coated and PtIr electrodes in rats, we show that improvements in signal quality with

The axisymmetric Rayleigh waves in a semi-infinite elastic solid
Theoretical and Applied Mechanics Letters, 2020 : It is well-known that Rayleigh wave, also known as surface acoustic wave (SAW), solutions in semi-infinite solids are plane waves with signatory properties like the distinct velocity and exponentially decaying deformation in the depth.

Acoustic Surface-Wave Recirculating Memory
IEEE Transactions on Sonics and Ultrasonics, 1972 An acoustic-surface-wave memory is described, operating at a bit rate of 220 MHz and storage capacity of 1280 bit per recirculation loop. The transducers are coded using orthogonal pairs of Golay complementary sequences to obtain pulse-in pulse-out behaviour.

Acoustic waves generated by the spin precession
, 2015 We study generation of acoustic waves by a precessing spin of a nanoparticle deposited on the surface of a solid. Our approach elucidates macroscopic dynamics of the Einstein - de Haas effect.
