© 2014 IEEE. An induction theorem-inspired approach is adopted for the design of a Huygens source nanoparticle laser. The proposed nanoparticle consists of a three-layer silicon-silver-silicon (Si-Ag-Si) concentric sphere, which enables the amplified and balanced excitation of the electric and magnetic dipole modes with scattering efficiencies in excess of 600. Moreover, with its dipolar modes designed to be in balance, its scattering directivity pattern is an almost perfect replica of the cardioid radiation pattern of a Huygens source, featuring Dscat = 3 in the forward direction and a null (Dscat ≃ 0) in the backward direction. Innovative electromagnetic force manipulation and trapping effects that are empowered with Huygens source nanoparticle lasers are considered.
