Introduction: A new method is proposed to obtain noise-free RF coil sensitivity maps. This is highly desirable, considering the fact that the sensitivity encoding (SENSE)[1] method imposes ultimate dependence of successful full FOV image reconstruction on the correct sensitivity map of each individual coil. The proposed method differs from traditional methods in that, instead of refining the me...

A wavelet-collocation scheme, constructed from the discrete singular convolution (DSC) is introduced for computational electromagnetics. The basic philosophy behind the DSC algorithm is studied. Four test problems, including waveguide analysis in both regular and irregular domains, electromagnetic wave scattering, electrostatic field estimation via potential functions, and electromagnetic wave ...

This paper describes how a spreadsheet program can assist electromagnetics education at the undergraduate level. Spreadsheet software has proven to be an important pedagogical tool for a variety of problems in electrical engineering education. Using the power of the 123 macros, a menu driven spreadsheet program is used to compute the solution of some electrostatic boundary value problems for an...

The advantages and disadvantages of Java for scientific programming are explored through the development of a Java applet for computational electromagnetics ~JACE!. Due to the complexity of systems modeled by computational electromagnetics, JACE is a good measure of performance for scientific programming. Java’s integration of graphics capabilities and numerical computations facilitates the dev...

A new globally convergent numerical method is developed for some multidimensional Coefficient Inverse Problems for hyperbolic and parabolic PDEs with applications in acoustics, electromagnetics and optical medical imaging. On each iterative step the Dirichlet boundary value problem for a second order elliptic equation is solved. The global convergence is rigorously proven and numerical experime...

Computational electromagnetics is a fascinating subject with plenty of opportunity still for scientific study and applied research. The commercial world can benefit from such work provided that it is useful, credible, and easy to adopt. My colleagues and I have sought a balanced approach in our work in communications engineering, pursuing contracts with industry while developing new computation...

By a highly–oscillating function we mean one with large number of local maxima and minima over some interval. The computation of integrals of highly–oscillating functions is one of the most important issues in numerical analysis since such integrals abound in applications in many branches of mathematics as well as in other sciences, e.g., quantum physics, fluid mechanics, electromagnetics, etc....

Abstract We introduce a new domain decomposition strategy for time harmonic Maxwell’s equations that is valid in the case of automatically generated subdomain partitions with possible presence cross-points. The convergence algorithm guaranteed and we present complete analysis matrix form method. method involves transmission matrices responsible imposing coupling between subdomains. discuss choi...
