In the past decades, Model Order Reduction (MOR) has demonstrated its robustness and wide applicability for simulating large-scale mathematical models in engineering and the sciences. Recently, MOR has been intensively further developed for increasingly complex dynamical systems. Wide applications of MOR have been found not only in simulation, but also in optimization and control. In this surve...

A framework for computational steering of a finite difference code for electromagnetic simulation has been developed and implemented. In computational steering we need to develop software which allows the user to enter an interactive visualization or VR environment and from there control the computation. A proof of concept implementation has been carried out using an existing code for 3D finite...

The exterior calculus of differential forms provides a mathematical framework for electromagnetic field theory that combines much of the generality of tensor analysis with the computational simplicity and concreteness of the vector calculus. We review the pedagogical aspects of the calculus of differential forms in providing distinct representations of field intensity and flux density, physical...

Keywords: ADI leapfrog method Meshless methods Smoothed particle electromagnetics a b s t r a c t Grid based methods coupled with an explicit approach for the evolution in time are traditionally adopted in solving PDEs in computational electromagnetics. The discretiza-tion in space with a grid covering the problem domain and a stability step size restriction, must be accepted. Evidence is given...

Advances in human brain neuroimaging for high-temporal and high-spatial resolution will depend on localization of Electroencephalography (EEG) signals to their cortex sources. The source localization inverse problem is inherently ill-posed and depends critically on the modeling of human head electromagnetics. We present a systematic methodology to analyze the main factors and parameters that af...

Berenger's perfectly matched layers (PML) has been found very e cient as a material absorbing boundary condition (ABC) for nite-di erence time-domain (FDTD) modeling of lossless media. In this paper, we apply the PML ABC to lossy media. The new ABC is shown to work excellently for lossy media too, provided that the appropriate PML pro les are selected. We nd that an e cient PML pro le is usuall...

| This paper describes an innovative new integrated lecture/laboratory course for electrical engineering juniors. The course, designed as the second course in a year-long sequence in electromagnetics, brings to life fundamental principles of electromagnetics through study of the circuit, signal, and system concepts used in today's wireless communication systems. The course is taught in a new la...

Abstract In the present study, a new methodology in computational electromagnetics is developed for two-dimensional arbitrarily-shaped objects with impedance boundary conditions. The proposed approach investigates E-polarized electromagnetic diffraction by object Leontovich condition. scattered electric and magnetic fields are expressed as convolution integral of corresponding Green’s function ...

Although near-field radiative heat transfer was introduced in the 1950's, interest field has recently revived, as effect promises improved performance various applications where contactless temperature regulation small-scale is a requirement. With progress computational electromagnetics well nanoinstrumentation, it become possible to simulate complex configurations and measure with high precisi...
