The quality factor of an RF cavity and the surface resistance are typically related with a constant geometry factor. implicit assumption made is that field independent, which however not observed experimentally in superconducting cavities. approximation error due to this becomes larger less homogeneous magnetic distribution along walls is. In paper we calculate for different types. An iterative method correct presented.
