Recent Trends in Computational Electromagnetics for Defence Applications

State-of-the-Art, Trends, and Directions in Computational Electromagnetics

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...

Recent Advances of Isogeometric Analysis in Computational Electromagnetics

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...

Ten Recent Trends in Computational Paralinguistics

The field of computational paralinguistics is currently emerging from loosely connected research in speech analysis, including speaker classification and emotion recognition. Starting from a broad perspective on the state-of-the-art in this field, we combine these facts with a bit of ‘tea leaf reading’ to identify ten trends that might characterise the next decade of research: taking into accou...

Distributed Computational Electromagnetics Systems

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...
