This book was released on 1973 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: An integral equation technique is employed to obtain eigenvalues and eigenmodes for a homogeneous Helmholtz equation for a two-dimensional or three-dimensional arbitrary closed region with arbitrary first order homogeneous boundary conditions. The integral approach has one dimension less than corresponding finite difference and finite element approaches. To demonstrate the method, an analytic solution is given for circular and spherical regions with a Dirichlet boundary condition and a Neumann boundary condition, and a solution procedure valid for any separable geometry is indicated. For an application to a non-separable boundary, a right triangle is considered as a two dimensional example. (Modified author abstract).

Download or read book Computational Methods for Electromagnetic and Optical Systems Second Edition written by John M. Jarem and published by CRC Press. This book was released on 2011 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text examines a variety of spectral computational techniques— including k-space theory, Floquet theory and beam propagation— that are used to analyze electromagnetic and optical problems. The authors tie together different applications in EM and optics in which the state variable method is used. Emphasizing the analysis of planar diffraction gratings using rigorous coupled wave analysis, the book presents many cases that are analyzed using a full-field vector approach to solve Maxwell’s equations in anisotropic media where a standard wave equation approach is intractable.

Download or read book Coupled Boundary and Finite Element Methods for the Solution of the Dynamic Fluid Structure Interaction Problem written by Siamak Amini and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text considers the problem of the dynamic fluid-structure interaction between a finite elastic structure and the acoustic field in an unbounded fluid-filled exterior domain. The exterior acoustic field is modelled through a boundary integral equation over the structure surface. However, the classical boundary integral equation formulations of this problem either have no solutions or do not have unique solutions at certain characteristic frequencies (which depend on the surface geometry) and it is necessary to employ modified boundary integral equation formulations which are valid for all frequencies. The particular approach adopted here involves an arbitrary coupling parameter and the effect that this parameter has on the stability and accuracy of the numerical method used to solve the integral equation is examined. The boundary integral analysis of the exterior acoustic problem is coupled with a finite element analysis of the elastic structure in order to investigate the interaction between the dynamic behaviour of the structure and the associated acoustic field. Recently there has been some controversy over whether or not the coupled problem also suffers from the non-uniqueness problems associated with the classical integral equation formulations of the exterior acoustic problem. This question is resolved by demonstrating that .the solution to the coupled problem is not unique at the characteristic frequencies and that it is necessary to employ an integral equation formulation valid for all frequencies.
