Gurevich in 2006 are actively discussed these years, because of their great possibility in reducing power consumptions and in enhancing RF breakdown field of the Sc RF cavity. On Apr. 2013, we submitted general formulae for the vortex penetration field of the Sc layer and the shielded magnetic field on the bulk Sc for a structure with a single Sc layer and a single insulator layer formed on a bulk Sc, by which a combination of the thicknesses of Sc and insulator layers that can realize the enhanced RF breakdown field can be found for any given materials. In this contribution, we will show progresses during the last year. Comparisons between the formulae and experimental results, and extended formulae for more realistic models, such as a model with surface defects, will be shown.
