Gold Antenna Above Magnetic Film #244

Closed Synergy0 closed 4 years ago

Synergy0 commented 4 years ago

I'm working on a project where I have a long thin strip of magnetic material with a gold antenna that lies on top of the strip at a 90 degree angle. There is an AC current going through the gold antenna at 9.5GHz which should generate spin waves in the strip. Is there a way in Mumax of modeling the gold antenna as a non-magnetic material that will generate the appropriate fields in the strip below?

Hi, you can do it using comsol and then implement it to the mumax.

For a simple antenna, you should be able to calculate the magnetic field analytically.
