Abstract: Withthedevelopmentofhighpowerandminiaturizationinsatellitepayload,accuratesimulationandthresholdanalysisformultipactorin complexcomponentbecomesbottleneckproblem.Basedontheparticleincelltechnologyandthesecondaryelectronemissiontheory,athreedimensionalsimulationmethodformultipactorwaspresented.Thenumericalalgorithmwasselfconsistentsincetheinteractionbetweenelectromagneticfieldsandparticleswasproperlymodeled.Thegenerationofmultipactoris visualized, sothat adeepinsightintothephysicalmechanismsofthiseffectwasgained.Inordertovalidatethemethod,multipactionintheimpedancetransformerwasstudied.Byanalyzingtheevolutionoftheelectronnumbersobtainedbyourmethod,multipactorthresholdsofthesecomponentswereestimatedandthemostsensitivepositionswheremultipactoroccurswerevisualized.Theresultsshowgoodagreementwiththeexperimentalresultsandthesimulationerrorislessthan1.2dB.
