The need for increasing fidelity and accuracy in mission-critical electromagnetic applications have pushed the problem sizes toward extreme computational scales. Therefore, there is a large premium placed on the investigation of parallel and scalable integral equation simulators, a particularly useful class of computational electromagnetics, to meet this demand. This dissertation will focus on ...

Grid-enabled portals are becoming increasingly popular for scientific collaboration. Specifically, a portal can be viewed as a Grid-based problem-solving environment (PSE) that allows scientists to access distributed resources, and to monitor and execute distributed Grid applications from a Web browser. This paper describes the Grid-enabled GECEM portal, which serves as a web gateway to computa...

Modeling electromagnetic (EM) fields and their interaction with a complex environment is important for developing safe and effective wireless systems. Methods for electromagnetic modeling are computationally intensive, and even small scenario can have long run times. Developments in graphics processing units (GPUs) over the past decade have created an attractive architecture for scientific comp...

The demand for computing power in computational electromagnetics (CEM) is continuously increasing. Meanwhile, cooperative engineering is becoming more and more present in daily research and development workflows. Projects are often developed by teams which interact remotely, and need tighter and tighter connectivity. Grid Computing seems a promising way to satisfy both the need of high-performa...

Periodic structures are of great importance in electromagnetics due to their wide range of applications such as frequency selective surfaces (FSS), electromagnetic band gap (EBG) structures, periodic absorbers, meta-materials, and many others.The aim of this book is to develop efficient computational algorithms to analyze the scattering properties of various electromagnetic periodic structures ...

Electromagnetic devices are ubiquitous in present day technology. Indeed, electromagnetism has found and continues to find applications in a wide array of areas, encompassing both civilian and military purposes. Among the former, applications of current interest include those related to communications (e.g. transmission through optical fiber lines), to biomedical devices and health (e.g. tomogr...

In this communication the advantages and drawbacks of the isogeometric analysis (IGA) are reviewed in the context of electromagnetic simulations. IGA extends the set of polynomial basis functions, commonly employed by the classical Finite Element Method (FEM). While identical to FEM with Nédélec’s basis functions in the lowest order case, it is based on B-spline and NonUniform Rational B-spline...

— Models in electromagnetism are more and more accurate. In some applications, the gap between the experience and the model comes from the deviation on input data of the model which are not perfectly known. The stochastic approach can be used to quantify the effect of these input data uncertainties on the outputs of the model. In this article, the application of such approach in computational e...

This paper presents a model order reduction method via Krylov subspace projection, for applications in the field of computational electromagnetics (CEM). The approach results to be suitable both for SISO and MIMO systems, and is based on the numerically robust Arnoldi procedure. We have studied the model order reduction as the number of inputs and outputs changes, to better understand the behav...
