Numerical solution of diffraction problems : a method of variation of boundaries by Oscar P Bruno(
Book
)
1 edition published in 1993 in English and held by 1 WorldCat member library worldwide
Abstract: "We present a new numerical method for the solution of the problem of diffraction of light by a doubly periodic surface. This method is based on a high order rigorous perturbative technique, whose application to singly periodic gratings was treated in the first two papers of this series. We briefly discuss the theoretical basis of our algorithm, namely, the property of analyticity of the diffracted fields with respect to variations of the interfaces. While the algebraic derivation of some basic recursive formulae is somewhat involved, it results in expressions which are easy to implement numerically. We present a variety of numerical examples (for bisinusoidal gratings), in order to demonstrate the accuracy exhibited by our method as well as its limited requirements in terms of computing power. Generalization of our computer code to crossed gratings other than bisinusoidal is in principle immediate, but the full domain of applicability of our algorithm remains to be explored. Comparison with results presented previously for actual experimental configurations shows a substantial improvement in the resolution of our numerics over that given by other methods introduced in the past."

Electromagnetic Scattering(
Book
)
2 editions published in 2001 in English and held by 1 WorldCat member library worldwide
The problems and techniques addressed under the present contract deal with issues of analysis and computation in electromagnetics. The primary goal consists of the development of efficient numerical tools for the prediction of scattered fields in a number of practical configurations. For this, substantial effort will be devoted to the extension and enhancement 0 the Method of Variation of Boundaries (MVB). Specific objectives in connection with MVB include: (1) advancement and implementation of algorithmic improvements for very highorder calculations; (2) application to the solution of eigenvalue problems (related to cavities, resonators and waveguides); to the calculation of electromagnetic scattering from damaged objects and rough terrain; and to inverse scattering problems. (3) Concurrent with these endeavors the program will pursue the incorporation of the boundaryvariation approach in more classical computational techniques, such as the finiteelement methods (FEM). A first instance of such interactions will be sought through the implementation of highorder boundary perturbation approximations to computational radiation conditions (typically imposed on separable geometries). To enable and enhance such applications, the plan includes the development of new (highorder) discontinuous Galerkin (DG) finite element approach to electromagnetic scattering calculations which is expected to provide an advantageous setting for adaptivity and parallelization. Alternative highorder methods (e.g., based on integral equation formulations) will also be considered

Partial Differential Equations from the Materials Sciences: Analysis and Computation(
Book
)
2 editions published in 1998 in English and held by 1 WorldCat member library worldwide
This report describes accomplishments in the areas of electromagnetic scattering and smart materials achieved under Grant No. F496209510113. With regards to problems of wave propagation, advances in the development of highorder perturbation methods are reported. These include the derivation and coding of algorithms for the numerical solution of the scalar and vector forward scattering problems for two and threedimensional configurations and the formulation of corresponding approaches to inverse scattering calculations and to the estimation of normal and quasinormal cavity modes. Concurrent achievements in the study of smart materials are also recounted here. They include the development of nonlinear homogenization theories intended to capture overall elastic behaviors (e.g., of shapememory alloys, SMA), or magnetic and rheological responses (such as those of magnetorheological fluids, MRF). The latter project was undertaken in collaboration with scientists at the Lord Corporation, the worldwide leader in MRF technology, and was geared towards the incorporation of advanced mathematical modeling and simulations into the design of MRF

Dynamic Simulation of the Temporal Response of Microstructure Formation in Magnetorheological Fluids(
)
1 edition published in 1999 in English and held by 0 WorldCat member libraries worldwide
Efficient numerical simulations of microstructure development in magnetorheological (MR) fluids are conducted. The simulations, which are based upon a fast multipole algorithm, treat the magnetic inclusions as twodimensional continuum magnetic entities. The development of microstructure is quantified by computing and recording the time evolution of the effective permeability of composite fluid. Such a principle has been previously exploited for the experimental measurements of microstructure development (Jolly, Bender and Mathers, ERMR'97, Yonezawa, Japan 1997). As was observed experimentally, numerical simulations reveal the evolution of microstructure to be multimodal in nature. Unlike the experiments, the numerical simulations afford us the ability to observe the physical mechanisms associated with various modes

Evaluation of HighFrequency Electromagnetic Scattering via HighOrder MultipleScattering Integral Asymptotics(
)
1 edition published in 2003 in English and held by 0 WorldCat member libraries worldwide
Report developed under STTR contract for topic AFOlTOO9. We introduced a new algorithm for the numerical solution of problems of electromagnetic or acoustic scattering in the highfrequency regime. This algorithm combines the use of an ansatz for the unknown density in a boundary integral formulation of the scattering problem with an extension of the ideas of the method of stationary phase. In particular, we obtained numerical results illustrating the high order convergence of our algorithm as well as its asymptotically bounded computational cost as the frequency increases
