The permeability (or relative permeability) is the measurement of the ability of a material to support the formation of a magnetic field within itself. If you increase the permeability, in my opinion, you modify the material's property (increase the Q factor) that it can store more energy from the applied magnetic field. Therefore, it should take longer time for the material to radiate the stored energy into free space. #cJ1Jj $

About verification, you may establish a RF resonance model, linearly increase the permittivity and/or permeability and I expect the following: |D;I>

1. Q factor is increased. 33"!K>wC  
2. Resonance frequencies moves toward lower frequency range. [w FK!?  
3. Bandwidth becomes narrower. aNICSxDN  
4. Slover takes longer time to meet the numerical noise level.
