SPARK3D is a unique simulation tool for determining the RF breakdown power level in a wide variety of passive devices, including those based on cavities, waveguides, microstrip and antennas. Field results from CST STUDIO SUITE® simulations can be imported directly into SPARK3D to analyse vacuum breakdown (multipactor) and gas discharge. From this, SPARK3D calculates the maximum power that the device can handle without causing discharge effects.
Typical approximate approaches to determine the RF breakdown power level of any component are intentionally extremely conservative. SPARK3D is based on advanced methods which analyse the breakdown phenomena numerically. SPARK3D can predict more realistic breakdown power levels, significantly improving the design margins.
