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...

Modern signal and array processing methods now incorporate the physics of wave propagation as an integral part of the processing. Matched field processing (MFP) refers to signal and array processing techniques in which, rather than a plane wave arrival model, complex-valued (amplitude and phase) field predictions for propagating signals are used. Matched field processing has been successfully a...

We describe our development of a \real world" electromagnetic application on distributed computing systems. A computational electromagnetics (CEM) simulation for radar crosssection(RCS) modeling of full scale airborne systems has been ported to three networked workstation cluster systems: an IBM RS/6000 cluster with Ethernet connection; a DEC Alpha farm connected by a FDDI-based Gigaswitch; and...

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...

Understanding the milliscale (temporal and spatial) dynamics of the human brain activity requires high-resolution modeling of head electromagnetics and source localization of EEG data. We have developed an automated environment to construct individualized computational head models from image segmentation and to estimate conductivity parameters using electrical impedance tomography methods. Algo...

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 ...

 Web-based learning tools are indispensable in modern teaching, especially when the ability to reveal extra information on demand is an excellent tool for stimulating and engaging students. The complexity of problems from the field of Electromagnetics makes understanding and study difficult for students. Visualization of phenomena, animations synchronized with corresponding derivation of equat...

In this paper, an innovative student seminar-based classroom practice is reported. The instructional process was illustrated by student-oriented theoretical inquiry of interested topics combined with traditional and emerging applications. Specifically, under the careful guidance of the instructor, every student or student group chose an EM topic of their interest and presented to the class; whi...
