In Memphis to Present ISMB Recent Developments on Computational Electromagnetics

2 July 2014

ISMB will participate in the 2014 edition of the IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, the largest and most important international symposium on antennas and propagation which will be held on July 6–11, 2014 in Memphis (Tennessee, USA). The symposium and meeting are cosponsored by the IEEE Antennas and Propagation Society (AP-S) and the US Committee of the International Union of Radio Science (USNC-URSI) Commissions A, B, C, D, E, F, G, and K. The joint meeting is intended to provide an international forum for the exchange of information on state-of-the-art research in antennas, propagation, electromagnetics, and radio science.

At the symposium, the Antenna and EMC (LACE) Unit – part of the Advanced and Computing & Electromagnetics (ACE) Research Area – will present three contributions, showing recent developments of the group in the field of Computational Electromagnetics (CEM), specifically aimed at the efficient and accurate EM modeling of large and complex structures:

  • a fast solver, namely “Wideband Nested Equivalent Source Approximation” (WNESA), based on a new factorization scheme of the involved integral operators, allowing for the analysis of geometries extending up to a few hundreds of wavelengths; 
  • a new domain decomposition method, to accelerate the EM analysis thanks to a subdivision of the simulation domain in smaller sub-domains, resulting in an intrinsically well suited algorithm for an efficient parallel implementation; 
  • the results of the activities carried out in the frame of the “Railwaves” project, partially funded by Piedmont Regional Government in the frame of the ICT Innovation Cluster. In the railway sector the rolling stock is built around bearings that support most of the mechanical strain; the project aims at realizing an onboard WSN capable of monitoring the working conditions of the bearings and of providing real-time warnings in case of faults.
