Numerical implementation of the MRC method for obstacle scattering problems
The goal of this work is to show that the numerical solution of the obstacle scattering problem based on the modified Rayleigh conjecture (MRC) method is a competitive alternative to the boundary integral equations method, and that it has numerical advantages which may be especially important in threedimensional scattering problems with non-smooth domains, for example, with domains whose bounda...

The goal of this work is to show that the numerical solution of the obstacle scattering problem based on the MRC (modified Rayleigh conjecture) method is a competitive alternative to the BIEM (boundary integral equations method), and that it has numerical advantages which may be especially important in three-dimensional scattering problems with non-smooth domains, for example, with domains whos...
متن کاملNumerical solution of obstacle scattering problems
Some novel numerical approaches to solving direct and inverse obstacle scattering problems are presented. Scattering by finite obstacles and by periodic structures is considered. The emphasis for solving direct scattering problem is on the Modified Rayleigh Conjecture method, recently introduced and tested by the authors. This method is used numerically in scattering by finite obstacles and by ...
متن کاملNumerical Method for Solving Obstacle Scattering Problems by an Algorithm Based on the Modified Rayleigh Conjecture
A numerical algorithm for solving obstacle scattering problems is presented. This algorithm is based on the Modified Rayleigh Conjecture (MRC) method introduced by A. G. Ramm. Its numerical implementation shows that the method is efficient, can handle nonsmooth 3D obstacles and obstacles with complicated shapes. Numerical examples are given.
متن کاملModified Rayleigh Conjecture Method for Multidimensional Obstacle Scattering Problems
The Rayleigh conjecture on the representation of the scattered field in the exterior of an obstacle D is widely used in applications. However this conjecture is false for some obstacles. AGR introduced the Modified Rayleigh Conjecture (MRC), and in this paper we present successful numerical algorithms based on the MRC for various 2D and 3D obstacle scattering problems. The 3D obstacles include ...
