To scatter or not to scatter [PDF]
Nature Materials, 2016 A rewritable platform for subwavelength optical components is demonstrated by combining surface phonon–polaritons, sustained in a polar dielectric layer, with the switching functionality provided by a phase-change material.

Parallel Processing Letters, 2009
In this paper, we investigate the scatter problem, which is defined as follows: Given a set of n robots, regardless of the initial position of the robots on the plane, eventually, no two robots are located at the same position forever. We show that this problem cannot be deterministically solved. Next, we propose a randomized algorithm.

Simultaneous Neutron Scattering and Raman Scattering
Applied Spectroscopy, 2009The capability to make simultaneous neutron and Raman scattering measurements at temperatures between 1.5 and 450 K has been developed. The samples to be investigated are attached to one end of a custom-made center-stick suitable for insertion into a 100 mm-bore cryostat.

Acoustical scattering by radially stratified scatterers
The Journal of the Acoustical Society of America, 2008A recursive solution procedure is developed to analyze the acoustical scattering by multilayer concentric circular cylindrical scatterers. The procedure is based on multiple scattering in the single-scatterer methodology originally proposed by one of the authors. The solution for a scatterer having an arbitrary number of layers is solved by recursively

Multiple scattering and scattering cross sections
The Journal of the Acoustical Society of America, 2018The scattering cross section for a cluster of scatterers can be calculated using various methods, either exactly or by invoking various approximations. Of special interest are methods in which the scattering properties of individual members of the cluster are used. The underlying question is: Can the contribution to the cluster's cross section from any

Multiple scattering in single scatterers
The Journal of the Acoustical Society of America, 2004Scattering by a multilayered scatterer is analyzed via a novel multiple-scattering approach. Based on the recognition that multiple scattering occurs within single scatterers having internal interfaces, the solution procedure follows the physical process, and yields analytically exact solutions.

Scattering and Inverse Scattering
1993For a given potential, the scattering method has been commonly used to find the wave functions in quantum mechanics. An inverse process of this scattering is to find the potential from known scattering data. Such a process is called the inverse scattering method. If the potential satisfies a nonlinear evolution equation (the differential equation u t =
