Spark3D — RF breakdown analysis software

RF breakdown analysis software

Spark3D is a unique simulation tool for determining the RF breakdown power level in a wide variety of passive devices, including cavities, waveguides, microstrip and antennas.

Simulia CST Studio Suite Spark3D is the most powerful software tool for RF breakdown analysis available on the market today. It is based on accurate numeric algorithms for predicting both gas discharge (also known as Corona discharge) and Multipactor breakdown onsets, which are two of the main high power effects that can severely damage passive RF devices. Spark3D supports the designing/manufacturing industries to decrease both the time to market and the development costs of the next generation of communication systems.

    Multipactor Analysis

    The Multipactor module is mainly based on an efficient full 3D electron tracker and a sophisticated electron emission model for the characterization of the surfaces. This technique allows the analysis of multipactor in complicated structures that involve arbitrary shapes in short computational times. Some of the most relevant features of the multipactor analysis in Spark3D are:

    • Automatic multipactor threshold determination;
    • Multipactor analysis in the case of single-carrier, multi-carrier and modulated signals;
    • Possibility of using predefined, user-defined and imported surface material properties;
    • Automatic optimum initial electron seeding distribution;
    • 3D output surface statistics to identify the discharge location and understand the nature of the discharge;
    • Possibility to add external electric and/or magnetic DC fields to the RF field;
    • Visualization of the electron motion in the device.

    Gas Breakdown (Corona Discharge) Analysis

    The Corona module in Spark3D uses a Finite-Element technique to solve the electron density continuity equation. This approach allows the accurate analysis of gas breakdown in complicated structures in short computational times. Some of the most relevant features of the corona analysis in Spark3D are:

    • Automatic breakdown threshold determination for a chosen pressure range;
    • Possibility of using different gasses: dry Air, Nitrogen, Helium, Argon, SF6 and CO2;
    • High pressure breakdown estimate based on a fast analytical calculation;
    • Analysis of corona discharge at a fixed input power;
    • Visualization of the discharge formation to identify the location of the breakdown.
