The modeling and solution of large-scale problems in computational electromagnetics (CEM) requires the application of the right tool for the right job in order to minimize the potential for error generation and propagation during each step of the process. The subtleties of this issue are associated with knowing where sources of error can arise, how to quantify them, and what methods can be used...

Two laboratory projects—a Doppler radar and a synthetic aperture radar (SAR)—designed to augment traditional electromagnetics education are proposed. The projects introduce students to component and system level design and expose them to modern computer-aided design (CAD) tools, microstrip and surface mount fabrication technologies, and industry standard test equipment and procedures. Additiona...

The development of technologies for the additive manufacturing, in particular metallic materials, is offering possibility producing parts with complex geometries. This opens up to using topological optimization methods design electromagnetic devices. Hence, a wide variety approaches, originally developed solid mechanics, have recently become attractive also field electromagnetics. general disti...

We propose an adaptive multigrid preconditioning technology for solving linear systems arising from Discontinuous Petrov–Galerkin (DPG) discretizations. Unlike standard techniques, this preconditioner involves only trace spaces defined on the mesh skeleton, and it is suitable hp-meshes. The key point of construction integration iterative solver with a fully automatic reliable refinement process...

With the advent of computational electromagnetics and increasing speed and power of computing, it is promising where modelling in microwave remote sensing can be pursued with more realistic physical configuration. This project focuses on new approaches in extending current basic computational electromagnetics to the application in microwave remote sensing as well as extension of modelling capab...

A scheme is presented for accurately propagating the gravitational field constraints in finite difference implementations of numerical relativity. The method is based on similar techniques used in astrophysical magnetohydrodynamics and engineering electromagnetics, and has properties of a finite differential calculus on a four-dimensional manifold. It is motivated by the arguments that 1) an ev...
