Ansys HFSS Multipaction and RF Discharge 

Course Overview

This course covers both Multipaction and RF Discharge analysis using Ansys HFSS. The multipaction part of this course explores multipaction in space borne communications systems and electron devices using the finite element method. This part of course consists of a lecture and five workshops with instructions and simulation files. The RF Discharge part of the course explores the ionization of gases due to high power RF signals in communications systems and electron devices using the finite element method. This part consists of a lecture and six workshops with instructions and simulation files.

Prerequisites

  •  Completion of the HFSS Getting Started course or equivalent familiarity with the HFSS 3D Modeler, workflow, solver setup, and post-processing (plotting results graphs).
  • Familiarity with physics related to multipaction and RF discharge

Teaching Method

Lectures and computer practical sessions to validate acquired knowledge.
