This video provides a step-by-step description of the multipaction setup inside Ansys HFSS. It includes the setup of the excitations, which depend on the electron density charge region and the SEY values at the vacuum boundary. This boundary can be a vacuum–conductor surface or a vacuum–dielectric surface. The SEY values can be customized to characterize any material. The correct setup of the excitation and boundary conditions are essential to the accuracy of the simulation.
Multipaction can cause damage to a satellite communication system in a vacuum environment. Learn how Ansys HFSS can help you predict when multipaction might occur.
