Hi

I am trying to simulate a 3d metamaterial cylinder. I build a cylinder and set its relative permeability as -1. the source is a coil inside it. However, the simulation does not converge. Does anyone have idea on this?

Also I tried positive permeability, it works well

You have to use Transition boundary condition on the metamaterial boundary when using negative refractive index, likewise this case www.comsol.com/model/modeling-a-negative-refractive-index-wave-optics-14687
