Here are shown below the major milestones which led to the actual EMC2020 software series:













    Phase-1: from 1984 to 1996 at Matra-Espace:matra-Marconi-Space under ESA & CNES contracts

    • “Radiate” software: Illumination of a cable through an aperture (time
      domain solution). Similar functions in TLS & BTLS EMC2020 softwares
    • “TWTD” software: 3d MoM solver for wire-frame like structures. An ersatz of the LLNL solver.
    • 3d MoM softwares for general geometries:
      •  “Maxsim-F” (frequency domain).
      • “MaxSim-T” (in the time domain). Planed to come back in EMC2020 with a 3d graphical interface.







    Phase-2: from 1984 to 1996 at Matra-Espace:matra-Marconi-Space under ESA & CNES contracts

    • “EMC2000” software: a 3d method of moments for surface/wire geometries with apertures & dielectric regions
    • Software distribution in CNES, ESA, European & japan industry















    Phase-3: from 2005 to 2012 At CCR-Aerospatiales/AIRBUS Research-center under European Community projects

    • Impove EMC2000-MoM software with hybriding (PO, Huygens/antenna sources, cavity Green’s dyadic, …)
    • Integration of the FMS solver: Out of Core solution for the linear system.)






    Phase-4: Stop of development & distribution of the EMC2000 software series from 2012 to 2019






    Phase-5: Since 2019: Development of the new EMC2020 software-series at EM-VisualTools




    1985
    Phase1: Radiate, TWTD, SGEMP/ESD

    No graphical interfaces. Developped under UNIX environment on SUN machines.

    "Radiate" Software:Transmission line solver via the FDTD method.

    • Simple lines with resistive termination.
    • Source is the field issued from an illuminated aperture.
    • Developped on Unix machines for the TDAS project.

    "TWTD" Software:3d WireFrame MPIE solver: an ersatz of the LLNL solver.

    • Voltage source or Impinging EM-source.
    • Time dependant loading conditions.

    "SGEMP/ESD" Software: 2d axy-symmetric FDTD with particle in cell method.
