Since modern high-performance computer systems consist of many hardware components and software layers, they present severe challenges for application developers who are primarily domain scientists and not experts with continually evolving hardware and system software. Effective tools for performance analysis are therefore decisive when developing performant scalable parallel applications. Such...

We summarize the activities conducted since 2019 in numerical electromagnetic analysis of one prototype station SKA-Low telescope. Working closely with SKA Observatory, two teams based Australia and Italy have collaborated effectively modeling analyzing AAVS2, which is most recent an installed Western Australia. A comprehensive overview main parameters at element array level obtained different ...

─ This paper presents a new method to model inhomogeneous media in commercial electromagnetics software, especially FEKO. In this method, the inhomogeneous medium is fragmented to some homogeneous pieces. If the size of these pieces is chosen correctly, then the electromagnetic behaviors of them and inhomogeneous medium are the same. Since creating these homogeneous pieces in FEKO manually is v...

The GECEM project is developing Grid technologies to enable large-scale and distributed engineering research in computational electromagnetics (CEM). We present a Web service portal architecture for supporting collaboration among distributed partners using the Grid. The GECEM grid takes a model geometry generated at one location, and transfers it to a second location to be meshed. The computati...

The key bottleneck of implicit computational electromagnetics tools for large complex geometries is the solution of the resulting linear system of equations. The goal of this effort was to research and develop critical numerical technology that alleviates this bottleneck for largescale computational electromagnetics (CEM). The mathematical operators and numerical formulations used in this arena...

Computational electromagnetics is a fascinating subject with plenty of opportunity still for scientific study and applied research. The commercial world can benefit from such work provided that it is useful, credible, and easy to adopt. My colleagues and I have sought a balanced approach in our work in communications engineering, pursuing contracts with industry while developing new computation...
