Wave scattering by many small particles embedded in a medium
A. G. Ramm
Theory of scattering by many small bodies is developed under various assumptions concerning the ratio , where is the characteristic dimension of a small body and $…
A recipe for making materials with negative refraction in acoustics
A. G. Ramm
A recipe is given for making materials with negative refraction in acoustics, i.e., materials in which the group velocity is directed opposite to the phase velocity. The recipe con…
Some Results on Inverse Scattering
A. G. Ramm
A review of some of the author's results in the area of inverse scattering is given. The following topics are discussed: 1) Property and applications, 2) Stable inversion of fi…
Materials with a desired refraction coefficient can be made by embedding small particles
A. G. Ramm
A method is proposed to create materials with a desired refraction coefficient, possibly negative one. The method consists of embedding into a given material small particles. Given…
Wave scattering by small impedance particles in a medium
A. G. Ramm
The theory of acoustic wave scattering by many small bodies is developed for bodies with impedance boundary condition. It is shown that if one embeds many small particles in a boun…
