In this work, the directional excitation of acoustic graphene plasmons (AGPs) are numerically studied using finite element methods. our proposed hybrid graphene-metal structure under oblique incidences, not only AGPs excited efficiently, but also they unidirectional propagating along a monolayer. Although symmetry dispersion relations broken by incidence, both left- and right-moved simultaneous...

The precedence effect (PE) is an auditory phenomenon involved in suppressing the perception of echoes in reverberant environments, and is thought to facilitate accurate localization of sound sources. We investigated physiological correlates of the PE in the inferior colliculus (IC) of anesthetized cats, with a focus on directional mechanisms for this phenomenon. We used a virtual space (VS) tec...

This paper reports a noncontact inspection method, using Pulsed Eddy Current (PEC) stimulated thermography, for the evaluation of the anisotropic dependency of electrical conductivity of steel exposed to tensile stress. This method combines microscope lens based thermography with PEC using a rectangular excitation coil, giving directional excitation, to infer the electromagnetic properties vari...

stimuli. We found that the space-time slant of the receptive field of directional simple cells differed for high and low contrast stimuli, with the space-time slant predicting higher optimum speeds for the higher contrast stimuli; i.e. there was a larger spatial shift of the receptive-field organization per unit time. Not only did the space-time maps of directional simple cells show different s...

Directional plasmon excitation and surface enhanced Raman scattering (SERS) emission were demonstrated for 1D and 2D gold nanostructure arrays deposited on a flat gold layer. The extinction spectrum of both arrays exhibits intense resonance bands that are redshifted when the incident angle is increased. Systematic extinction analysis of different grating periods revealed that this band can be a...

High refractive index dielectric nanoparticles show high promise as a complementary nanophotonics platform due to compared with plasmonic nanostructures low absorption losses and the co-existence of magnetic and electric resonances. Here we explore their use as resonantly enhanced directional scatterers. We theoretically demonstrate that an asymmetric dimer of silicon nanoparticles shows tuneab...

Wave Energy Converter (WEC) performance is generally sensitive to the wave direction. So, it important include effect of multi-directional waves in numerical modelling. A realistic representation ocean should account for height and directional spreading parameters specific WEC deployment location. high quality generalised distribution dependent on direction frequency. Here we compare power prod...
