  • WAVE SCATTERING THEORY FOR SMALL BODIES OF ARBITRARY SHAPES
    RAMM ALEXANDER G
    The book is a research monograph by the author, presenting significant results with important applications in materials science. For example, it introduces a method for designing materials with a desired refraction coefficient - a method whose very existence was previously unknown.This method is based on the author’s original theory for solving many-body scattering problems in ...

  • WAVE SCATTERING BY SMALL BODIES
    ALEXANDER G RAMM / RAMM ALEXANDER G
    The book is a research monograph. An asymptotically exact solution of the many-body scattering problem is given under the assumption a ≪ d ≪ λ, where a is the characteristic size of a small particle, d is the smallest distance between particles and λ is the wavelength in the medium in which the particles are embedded. Scattering of scalar and electromagnetic waves is considered...

  • Analysis of the Navier-Stokes Problem
    Alexander G. Ramm
    This book revises and expands upon the prior edition,  The Navier-Stokes Problem. The focus of this book is to provide a mathematical analysis of the Navier-Stokes Problem (NSP) in R^3 without boundaries.  Before delving into analysis, the author begins by explaining the background and history of the Navier-Stokes Problem. This edition includes new analysis and an  a priori  es...

  • The Navier-Stokes Problem
    Alexander G. Ramm
    The main result of this book is a proof of the contradictory nature of the Navier‒Stokes problem (NSP). It is proved that the NSP is physically wrong, and the solution to the NSP does not exist on ℝ+ (except for the case when the initial velocity and the exterior force are both equal to zero; in this case, the solution ����(����, ����) to the NSP exists for all ���� ≥ 0 and ���...

  • Symmetry Problems
    Alexander G. Ramm
    This book gives a necessary and sufficient condition in terms of the scattering amplitude for a scatterer to be spherically symmetric. By a scatterer we mean a potential or an obstacle. It also gives necessary and sufficient conditions for a domain to be a ball if an overdetermined boundary problem for the Helmholtz equation in this domain is solvable. This includes a proof of ...

  • Creating Materials with a Desired Refraction Coefficient
    Alexander G. Ramm / Alexander GRamm
    Creating Materials with a Desired Refraction Coefficient’ provides a recipe for creating materials with a desired refraction coefficient, and the many-body wave scattering problem for many small impedance bodies is solved. The physical assumptions make the multiple scattering effects essential. On the basis of this theory, a recipe for creating materials with a desired refracti...

  • Iterative Methods for Calculating Static Fields and Wave Scattering by Small Bodies
    Alexander G. Ramm
    Iterative methods for calculating static fields are presented in this book. Static field boundary value problems are reduced to the boundary integral equations and these equations are solved by means of iterative processes. This is done for interior and exterior problems and for var­ ious boundary conditions. Most problems treated are three-dimensiona...
