Directional Reflective Surface Formed via Gradient-Impeding Acoustic Meta-Surfaces
Artificially designed acoustic meta-surfaces have the ability to manipulate sound energy to an extraordinary extent. Here, we report on a new type of directional reflective surface consisting of an array of sub-wavelength Helmholtz resonators with varying internal coiled path lengths, which induce a reflection phase gradient along a planar acoustic meta-surface. The acoustically reshaped reflec...
متن کاملAutomatic Face Recognition via Local Directional Patterns
Automatic facial recognition has many potential applications in different areas of humancomputer interaction. However, they are not yet fully realized due to the lack of an effectivefacial feature descriptor. In this paper, we present a new appearance based feature descriptor,the local directional pattern (LDP), to represent facial geometry and analyze its performance inrecognition. An LDP feat...
متن کاملDirectly reflective meta-programming
Existing meta-programming languages operate on encodings of programs as data. This paper presents a new meta-programming language, based on an untyped lambda calculus, in which structurally reflective programming is supported directly, without any encoding. The language features call-by-value and call-by-name lambda abstractions, as well as novel reflective features enabling the intensional man...
متن کامل1d-localization of Surface Acoustic Waves by Quasiperiodically Corrugated Surfaces
Specific properties of the propagation of surface acoustic waves on quasiperiodically corrugated solids are reviewed. This problem corresponds to the critical regime of the Anderson localization transition, characterized by critical proper modes which are neither extended nor localized and which exhibit remarkable scaling features. The spectrum is also predicted to have a Cantor-like structure....
متن کاملFocusing of surface-acoustic-wave fields on „100... GaAs surfaces
Focused surface-acoustic waves ~SAWs! provide a way to reach intense acoustic fields for electroand optoacoustic applications on semiconductors. We have investigated the focusing of SAWs by interdigital transducers ~IDTs! deposited on ~100!-oriented GaAs substrates. The focusing IDTs have curved fingers designed to account for the acoustic anisotropy of the substrate. Different factors that aff...
