Overview • Lectures • The remaining lectures are split into several sections:



– Chapter 3: HFSS 3D – Chapter 4: HFSS Layout – Chapter 5: 3D Modeler – Creating 3D Components – Chapter 6: Appendix Intermediate and Advanced HFSS topics Chapter 3 and Chapter 4 are independent of each other. If you have already identified that you are only interested in one of the two design entries techniques, you can focus on the appropriate chapter.

• Workshops • Example designs with step-by-step instructions are available to reinforce the content covered in the lectures. • The workshops follow the chapter ordering for HFSS 3D and HFSS 3D Layout
