Difference between MEF and EMW frequency study

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?

There is overlap between the two modules of ac/dc and emw. You can read this for more info as it was written better than I can do here:
