Acoustic Metamaterial Design and Applications By
We proposed an approach to construct a 2D Fresnel lenses by acoustic network. This lens iscomposed of an array of Helmholtz resonators. The resonance at individual resonators results ineffective focusing even the plate has subwavelength thickness. The FEM simulation resultspresented the ultrasonic wave propagation through the lenses together with the resultingdiffraction pat...
متن کاملDesign of an acoustic metamaterial lens using genetic algorithms.
The present work demonstrates a genetic algorithm approach to optimizing the effective material parameters of an acoustic metamaterial. The target device is an acoustic gradient index (GRIN) lens in air, which ideally possesses a maximized index of refraction, minimized frequency dependence of the material properties, and minimized acoustic impedance mismatch. Applying this algorithm results in...
متن کاملBroadband Acoustic Hyperbolic Metamaterial.
In this Letter, we report on the design and experimental characterization of a broadband acoustic hyperbolic metamaterial. The proposed metamaterial consists of multiple arrays of clamped thin plates facing the y direction and is shown to yield opposite signs of effective density in the x and y directions below a certain cutoff frequency, therefore, yielding a hyperbolic dispersion. Partial foc...
متن کاملDouble-negative acoustic metamaterial.
We show here the existence of acoustic metamaterial, in which both the effective density and bulk modulus are simultaneously negative, in the true and strict sense of an effective medium. Our double-negative acoustic system is an acoustic analogue of Veselago's medium in electromagnetism, and shares many unique consequences, such as negative refractive index. The double negativity in acoustics ...
متن کاملA Systematic Approach to Photonic Crystal Based Metamaterial Design
Photonic crystal design procedure for negative refraction has so far been based on trial and error. In this paper, for the first time, a novel and systematic design procedure based on physical and mathematical properties of photonic crystals is proposed to design crystal equi-frequency contours (EFCs) to produce negative refraction. The EFC design is performed by the help of rectangular stair-c...
