Circular Sound Wave Scattering Derivation for Acoustic Cloak Detection
Circular Sound Wave Scattering Derivation Acoustic Cloak Detection Classical Physics
2012/5/29
In this Letter we develop analytical formulations to describe sound scattering in lossless medium due to 2D circular wave incident on an acoustic cloak. A perfect acoustic cloak is reflectionless and ...
Nonlinear Bose-Einstein-condensate Dynamics Induced by a Harmonic Modulation of the s-wave Scattering Length
Nonlinear Bose-Einstein-condensate Dynamics Induced Harmonic Modulation the s-wave Scattering Length
2011/9/15
In a recent experiment, a Bose-Einstein condensate of 7Li has been excited by a harmonic modulation of the atomic s-wave scattering length via Feshbach resonance. By combining an analytical perturbati...
Electromagnetic wave scattering by a thin layer in which many small particles are embedded
electromagnetic waves wave scattering by many small bodies
2011/1/21
Scattering of electromagnetic (EM) waves by many small particles (bodies), embedded in a thin layer, is studied. Physical properties of the particles are described by their boundary impedances.

In this paper the author’s invited plenary talk at the 7-th PACOM (PanAfrican Congress of Mathematicians), is presented.
Dynamical charge and spin density wave scattering in cuprate superconductor
Dynamical charge spin density wave cuprate superconductor
2010/11/19
We show that a variety of spectral features in high-Tc cuprates can be understood from the coupling of charge carriers to some kind of dynamical order which we exemplify in terms of fluctuating charge...
s-wave scattering and the zero-range limit of the finite square well in arbitrary dimensions
s-wave scattering zero-range limit finite square arbitrary dimensions
2010/10/19
We examine the zero-range limit of the finite square well in arbitrary dimensions through a systematic analysis of the reduced, s-wave two-body time-independent Schr¨odinger equation. A natural conseq...
Electromagnetic wave scattering by many small particles and creating materials with a desired permeability
electromagnetic waves wave scattering by many small bodies
2010/12/15
Scattering of electromagnetic (EM) waves by many small particles (bodies) embedded in a homogeneous medium is studied. Physical properties of the particles are described by their boundary impedances.

Wave scattering by undulating bed topography in a two-layer ocean
two-layer ocean wave scattering bottom undulations reflection transmission coefficients
2011/9/13
The problem of wave scattering by undulating bed topography in a two-layer ocean is investigated on the basis of linear theory. In a two-layer fluid with the upper layer having a free surface, there e...
A Formal Theory of Internal Wave Scattering with Applications to Ocean Fronts
Internal Wave Scattering Ocean Fronts
2009/2/10
A concise theory for scattering of internal waves at localized inhomogeneities (i.e., topographic features, baroclinicity in the density field, variations of the mean sea level, jetlike currents) in t...
Shelf Wave Scattering due to Longshore Jump in Topography
Shelf Wave Scattering Longshore Jump Topography
2009/1/5
The scattering of barotropic shelf waves by an abrupt jump in longshore topography is examined for unbounded and bounded exponential shelves by matching modal representations for longshore transport a...
Implications for Ocean Mixing of Internal Wave Scattering off Irregular Topography
Ocean Mixing Internal Wave nonlinear interactions geometric effects
2009/1/5
Earlier work has suggested that internal wave reflection off sloping bottoms may cause significant diapycnal mixing in the deep ocean, and may also represent an important sink of internal wave energy....
Continental Shelf Wave Scattering by a Rigid Barrier Normal to the Coast
Continental Shelf Wave Rigid Barrier Normal Coast
2008/12/30
In this paper we consider the scattering of continental shelf waves by a rigid barrier, within the context of the nondivergent, barotropic approximation. An incident wave mode encounters a rigid barri...
