    The Characteristic Mode formulation for dielectrics solved with the surface equivalence principle (SEP) results in a set of eigen modes that contains both internal and external resonances. The internal modes (sometimes call non-physical or fictitious) do not radiate any power, and are thus removed from the result set. It is advised to increase the number of modes requested when dealing with such models.
