Abstract :
The determination of the resonances of a PEC (perfectly electrically conducting) sphere embedded in an eccentric spherical dielectric shell is considered. Generally, the structure is PEC object with a nonuniform dielectric coating. When the eccentricity equals zero, the scatterer degenerates to a uniformly coated PEC sphere. Some numerical results are given.<>
