| Abstract: | We show that dielectric spherical and cylindrical particles contaminated with a metallic inclusion have similar spectral resonant behavior. Both geometries show resonance suppression as the position of the inclusion varies. Moreover, it was theoretically observed that the spherical particle suppresses a resonant mode earlier than the cylindrical one. Based on semi-classical arguments, a physical interpretation of this fact is given. In addition, a comment is also made regarding Wiscombe's criteria for estimating the size of the coefficient matrix used to solve the truncated non-homogeneous set of linear equations related to this problem. |
