There are two different physics interfaces Magnetic and Electric fields interface in ACDC module and Electromagnetic Fields, Frequency domain interface in RF module.
As I understood from the manual, both interfaces work without any static assumptions in frequency domain analysis.
MEF interface uses Maxwell-Ampère's law with displacement current included. And using the constitutive relations and equation of continuity it obtains two equations in terms of A and V and solves for these variables.
EMW interface solves for the wave equation.
These two methods seems equivalent to me. Are there any difference between them when used with a frequency domain study?
