Generalized Surface Admittance Equivalence Principle for Non-radiating and Super-scattering Problems
conference paper
Using Mie theory, the external scattering coefficients cm can be controlled for any m harmonic by a general equation for a dielectric cylindrical particle, generalizing previous results for single-harmonic cloaking. A multiharmonic non-radiating source and super-scattering particle can be produced by the insertion of a proper surface admittance needed at the boundary between dielectric and background region. Three separate limiting cases for non-radiating source and super-radiating features are presented and compared for the same bare particle case, with insights on the multi-harmonics suppression or enhancing of monopole, dipole, quadrupole radiation pattern and so on. In a straightforward manner, non-radiating and super-scattering sources can be created with future implementation with active or passive thin metasurfaces.
