    CEM One

    CEM One

    A Complete Environment for Computational Electromagnetics (CEM)

    CEM One is a consolidated software package with its first commercial shipment in December 2012, combining the best of Computational Electromagnetics, namely PAM-CEM Simulation Suite and Efield Solutions.

    PAM-CEM Simulation Suite operates mainly from medium to high frequency range. When targeting a wide frequency spectrum as usually managed with EMC/EMI issues, time-domain techniques are applied to investigate electromagnetic phenomena appearing along those complex cables networks connecting onboard electronics.

    Efield Solutions is primarily frequency-domain oriented with focus on antennas and scattering, making the overall solution fully consistent. ESI acquired Efield end of the year 2011.

    A Complete Environment for Computational Electromagnetics (CEM)

    The consolidated solution emphasizes a coupling and hybridization strategy, extending much beyond previous limits with larger models, higher operating frequencies, and more sophisticated scenarios, taking electromagnetic modeling one step further.

    CEM Solutions

    CEM One targets the following industries:

    Automotive & Ground transportation

    • EMC/EMI with internal cabling
    • Active Safety & Radar devices
    • Antenna placement, optimization, and other coupling phenomena

    Aeronautics & Defense

    • Radar signature and stealth
    • Thunder lightning
    • EMC/EMI with internal cabling
    • Antenna integration

    CEM One features the following components:

    EMC/EMI with Cable networks

    • 3D explicit Finite Difference Time Domain with PAM-CEM/FD
    • MultiConductor Transmission Lines (MTL) with CRIPTE
    • Dedicated 3D/MTL coupling procedures to handle realistic scenarios gathering both conducted & radiated EM phenomena

    Antenna placement & Radar signature

    • MoM/MLFMM solver technology in Frequency Domain
    • MDMM decomposition techniques to solve larger problems faster
    • Dedicated MoM/MLFMM-PO & FDTD-FEM hybrid techniques
    • PAM-CEM/HF PO (Physical Optics) solver for high-frequency scattering
    • FDTD-PO extension for radiated near fields

    Visual CEM 8.5

    Visual-CEM is a part of ESI’s virtual prototyping platform – Virtual Integration Platform.

    Virtual Integration Platform is a process oriented engineering approach much beyond solving multiple problems at a time. It is a single environment with a capacity to not just chain several simulation designs & results but also bring them into fully customized models suiting customer’s demand.
