Dispersion relation of vertical directional coupler

[Sreya Pal]

Hi everyone,

I am working on extracting the dispersion relation of a vertical directional coupler using MuMax3. I followed the simulation and post-processing procedure described in Example 5 of the MuMax3 post-processing documentation.

However, I am unable to reproduce the dispersion results reported in the following paper:

Magnetic field-controlled nanoscale spin-wave vertical directional coupler,
Applied Physics Letters 126, 232404 (2025)
DOI: 10.1063/5.0258034

I would be grateful for any suggestions regardingnany MuMax-specific considerations for vertically coupled structures.

Thank you very much for your help.

Regards,
Sreya

Hi, how exactly did you try to obtain the dispersion? Which parameters did you use in simulation? Your simulation script would be something that would help other people in helping you. Postprocessing script would be a good addition. Without them, you wouldn't be able to hear anything other than general recommendations.
