On the steering of sound energy through a supercritical plate by a near-field transducer array.
The ability to direct sound energy through the flexural vibrations of a submerged plate at various angles of incidence using a near-field transducer array is investigated. An alumina bar is placed in front of a one-dimensional, eight-element transducer array, between the array and the water. Operating in a receive mode, data were taken as a function of angle of incidence and compared to data ta...
متن کاملPlasmonic near-field transducer for heat-assisted magnetic recording
Plasmonic devices, made of apertures or antennas, have played significant roles in advancing the fields of optics and opto-electronics by offering subwavelength manipulation of light in the visible and near infrared frequencies. The development of heat-assisted magnetic recording (HAMR) opens up a new application of plasmonic nanostructures, where they act as near field transducers (NFTs) to lo...
متن کاملThe Sound Port: Development of Abi-directional Sound Transducer
The realisation of a functional Sound Port would be aided considerably if a bi-directional transducer were available. Electrodynamic transducers are capable of being used as the basis of a such a transducer. An analogue circuit model has been established which can be used to simulate both directions of their operation with reasonable accuracy. An 'in progress' design for a method of recovering ...
متن کاملNear-field intensity correlations in semicontinuous metal-dielectric films.
Spatial intensity correlation functions are obtained from near-field scanning optical microscope measurements of semicontinuous metal-dielectric films. The concentration of metal particles on a dielectric surface is varied over a wide range to control the scattering strength. At low and high metal coverages where scattering is weak, the intensity correlation functions exhibit oscillations in th...
متن کاملSound Effect Metaphors for near Field Distance Sonification
This article presents a concept of distance sound source sonification for virtual auditory displays in the context of the creation of an assistive device for the visually impaired. In order to respond to user needs, three sonification metaphors of distance based on sound effects were designed. These metaphors can be applied to any type of sound and thereby satisfy all aesthetic desires of users...
