A question about the correct boundary conditions

Hi

I'm currently modeling a microwave oven. Inside the chamber is a titanium cylinder, surrounded by a susceptor in zinc oxyde. All of this is surounded by a stationary TE10 wave.

I was wondering what boundary condition I should be placing on my titanium layer. I've currently chosen a scattering boundary, but I'm not sure if it's the right one or if I've set it up correctly. Any thoughts would be greatly appreciated.

Regards,

Greg Satre

Hi Greg,

as skin depth is very small in the metal (at 2.45 GHz?) you should place an impedance BC. If you leave it default, you have to mesh very fine in the surface layer to resolve the skin depth.

Scattering is not the right BC I think.

Cheers
Edgar

I am indeed working with 2.45GHz, sorry for not mentionning that. Thank you for your input, I'll try that out.
