  1. Computational Electromagnetics in Europe: Competition versus cooperation Prof. Guy Vandenbosch, Prof. R. Gillard K.U. Leuven, Belgium, IETR Rennes, France

  2. The situation The problem The ASI questions The partners The ACE answers The future Contents

  3. the commercial software vendors: competition in-house developed codes by (larger) companies Thales (France), France Telecom (France), Saab Ericsson Space AB (Sweden), … in many cases mainly for internal use very interested in standardisation a rich wealth of in-house made codes at universities and research institutes sometimes very specialized in many casesoutperforming the commercial codes … order of magnitude: a few 100 research groups in Europe enormous investment of time and money very interested in cooperation The situation

  4. the return on this huge investment of time and money is low example of Green’s functions example of matrix solvers The problem

  5. What do we have ? inventory What is the quality ? benchmarking How can we make it better ? software standardization and integration The questions

  6. universities: 14 KUL (B), CNRS-LEAT (F), IETR (F), SAPIENZA (I), POLITO (I), UNIFI (I), UNISI (I), UPC (E), UPM (E), UPV (E), CHALMERS (S), EPFL (CH), UOB (UK), ENST (F) industry: 7 IDS (I), TICRA (DK), FT(F), TAS (F), IMST (D), FOI (S), SATIMO (F) The partners

  7. description of the software of the partners agreed format open to anyone at the VCE (www.antennasvce.org) The ACE answers:Inventory

  8. well-defined agreed democratic protocols implemented through SOFTLAB, a web based application within the VCE open to anyone, after registration within the ACE community www.antennasvce.org The ACE answers:Benchmarking

  9. first run elements, open 14 partners, 18 tools, 36 simulations second run finite arrays, blind 8 structures, 14 partners + 2 vendors, 17 tools, 28 simulations third run (still going on) environment 5 structures The ACE answers:Benchmarking

  10. Benchmarking array with waveguide feed spherical conformal array large reflect array printed array with tight coupling dipole with lossy cylinder

  11. Where do we stand … Benchmarking Rangestar Ultima World GSM antenna 38 mm x 12 mm

  12. standardization: cooperation with ESA-ESTEC 6 Data Dictionaries: GFs, currents and meshes, near fields, modes, S-parameters, far fields EDI routines for currents and meshes, near fields, and far fields fortran, C, matlab adopted as standard by TICRA, SATIMO, THALES + ESA-ESTEC, SAAB-ERICSSON software library: implementation of EDI routines in software of 15 partners ca. 10 integration projects The ACE answers:Integration

  13. examples of integration projects: “Integration of UPC-UAB fast solvers into the antenna simulation software of UNEX-UPM, KUL, UPV, and EPFL ACE partners” “Fast analysis of large finite arrays with a combined multiresolution – fast MoM based techniques” “Applications of the DG-FDTD method” The ACE answers:Integration

  14. Integration activity betweenKUL (Belgium) and POLITO (Italy) (2) condition number of coupling matrix

  15. Deliverable of ACE European Association on Antennas and Propagation Newly formed non-profit organization, based in Brussels EurAAP

  16. WG 1 on standardization WG 2 on benchmarking WG 3 on European Software Library Proposal for a Softwaredepartment within EuRAAP

  17. an already committed group (KUL, IDS, SATIMO, THALES, TICRA) + (ERICSSON + ESA-ESTEC + IT-Link) open for other partners concrete plan with goals, time schedule, actions required, … organized around 4 topics short term evolution: TICRA standardization: SATIMO user community: KUL long-term management: IDS WG 1: Standardization

  18. “survival” budget: 11 KEuro my personal opinion based on 4 years ACE experience maintainance of and help desk for EDI routines: in case VCE is up and running absolute minimum 1-2 pm / year (11 - 22 kEuro) further extension of EDI: upgrade of existing and selection of other DDs this is a matter of group discussion in the right forum my proposal: specific session at EuCAP budget: 0 KEuro implementation of EDI routines for these DDs order of magnitude: 1 – 2 pm per DD (11 – 22 KEuro) potential income: yes licensing, support fee, … academic output: not really WG 1: Standardization

  19. a protocol on a periodic (yearly) benchmark cycle has been approved within the ASI community organized around EuCAP democratic selection process of structures to consider SOFTLAB is being extended with the necessary features “survival” budget: 0 KEuro further extension of SOFTLAB ? the organization around EuCAP (and COST ASSIST ?) eliminates most of the possible costs can be completely organized based on commitment, based on the ACE experience, this is very well feasible potential income: not really academic output: yes WG 2: Benchmarking

  20. within ASI up to now only the direct way has been followed in all integration projects WG 3: Antenna Software Library triangle of effort EDI in software isolated software integrated software

  21. distributed library This is why we do it …this produces the scientific, innovating papers established, large academic interest integration projects of ACE: “natural drive” of the partners already several papers at EuCAP 2006 and 2007 “survival” budget: 0 KEuro bilateral or multilateral can be connected with WG 5 of COST ASSIST: no real cost difference with situation before ACE: integration is much easier with the EDI potential income: not really academic output: huge possibilities WG 3: Antenna Software Library

  22. “downloadable” library Advantages reduced development time for new Ph.D. students, research groups reduced dependency of research on commercial tools More difficult issues competition for commercial solvers what do we do for researchers outside Europe “survival” budget: ??? start with “current and field viewer”, “mesher”, … potential income: absolutely licensing, support fee, … academic output: huge possibilities WG 3: Antenna Software Library

  23. Two antennas met on the roof and felt they were “matched” to each other. So they decided to get married. The wedding ceremony was ok, but the reception was excellent … Bad antenna joke …
