Three-dimensional collimated self-accelerating beam through acoustic metascreen
We report the generation of three-dimensional acoustic collimated self-accelerating beam in non-paraxial region with sourceless metascreen. Acoustic metascreen with deep subwavelength spatial resolution, composed of hybrid structures combining four Helmholtz resonators and a straight pipe, transmitting sound efficiently and shifting fully the local phase is evidenced. With an extra phase profil...
متن کاملOutsourcing through Three-dimensional Competition
In this paper, we study an outsourced supply chain consisting of one buyer and two suppliers in which the buyer outsources manufacturing of a physical product to two competing suppliers. The suppliers compete for the buyers' demands share, and the buyer allocates the demands to the competing suppliers based on three-dimensional allocation functions. We consider two certain types of allocation f...
متن کاملThree-dimensional accelerating electromagnetic waves.
We present a general theory of three-dimensional non-paraxial spatially-accelerating waves of the Maxwell equations. These waves constitute a two-dimensional structure exhibiting shape-invariant propagation along semicircular trajectories. We provide classification and characterization of possible shapes of such beams, expressed through the angular spectra of parabolic, oblate and prolate spher...

متن کاملThree-dimensional Acoustic Source Mapping
When beamforming is applied for acoustic source mapping, the sound pressure contributions of any sound sources are most often mapped to a planar or a surface map. However, some practical applications would benefit from a three-dimensional mapping, where the map consists of a three-dimensional grid. It is shown that the extension of microphone array beamforming techniques to three-dimensional ma...
