Waves around almost periodic arrangements of scatterers: Analysis of positional disorder
نویسندگان
چکیده
Much is known about the propagation of waves through periodic arrangements of identical scatterers, such as through a photonic crystal. Here, we consider a simple realization: scalar waves through a regular two-dimensional array of identical small circles. We are interested in the effect of random disorder: the circles remain identical, but their centres are given small random displacements. We derive asymptotic approximations that can be used to quantify the effect of positional disorder. Extension to more complicated problems seems feasible and is expected.

Two-dimensional Waves Around Almost Periodic Arrangements of Scatterers∗
Acoustic waves around an infinite configuration of identical circular scatterers are considered. Each scatterer is close to a node of a regular lattice: the geometrical configuration is almost periodic. Analytical estimates for the average field in such a random medium are obtained. Introduction Consider waves in a two-dimensional periodic structure, defined by a lattice Λ: each cell in the lat...
متن کاملOptimization of non-periodic plasmonic light-trapping layers for thin-film solar cells.
Non-periodic arrangements of nanoscale light scatterers allow for the realization of extremely effective broadband light-trapping layers for solar cells. However, their optimization is challenging given the massive number of degrees of freedom. Brute-force, full-field electromagnetic simulations are computationally too time intensive to identify high-performance solutions in a vast design space...
متن کاملSpectral Analysis of Wave Propagation through Rows of Scatterers via Random Sampling and a Coherent Potential Approximation
A method is proposed to determine the modal spectra of waves supported by arrays, which are composed of multiple rows of scatterers randomly disordered around an underlying periodic configuration. The method is applied to the canonical problem of arrays of identical small acoustically-soft circular cylinders, and disorder in the location of the rows. Two different approaches are adopted to calc...
متن کاملInfluence of positional correlations on the propagation of waves in a complex medium with polydisperse resonant scatterers.
We present experimental results on a model system for studying wave propagation in a complex medium exhibiting low-frequency resonances. These experiments enable us to investigate a fundamental question that is relevant for many materials, such as metamaterials, where low-frequency scattering resonances strongly influence the effective medium properties. This question concerns the effect of cor...

In this paper, the phase properties of waves reflected from one-dimensional double-periodic quasi-crystals consisting of single-negative materials are investigated using transfer matrix method. It is observed that, by increasing the double-periodic generation number, a large omnidirectional band gap is created in the single-nagative frequency range. We limit our studies to the frequency range o...
