报告摘要：In this talk, we are concerned with the electromagnetic wave generated by a hybrid dimer (composed of two closely coupled nano-particles with one plasmonic and the other dielectric), which can polarize both the incident electric and magnetic fields. Consequently, such hybrid dimers have the potential to modify both the electric permittivity and magnetic permeability of the surrounding medium if the two nano-particles share common resonant frequencies. We derive the asymptotic expansion of the fields generated by these hybrid dimers in the subwavelength regime for incident frequencies near their shared resonant frequencies.
