HFSS 3D Layout Technical Notes

The basis for the simulation technique that is used to calculate the S-parameters and radiated fields for a structure is the mixed potential integral equation (MPIE). Although the MPIE implementation is largely transparent, it helps to have a general understanding of this method to effectively use it in the Ansys Electronics Desktop (AEDT)^TM electronics systems design platform. The following topics provide an overview of the MPIE method, its implementation, and a description of how S-parameters are computed:

• The MPIE Method
• The Adaptive Analysis Process
• Ansys Fast Solver Technology
• EMI Scanner
• HFSS 3D Layout S-Parameters
• HFSS 3D Layout Modes
