In this Review, the theory and applications of optical micro‐and nano‐resonators are
presented from the underlying concept of their natural resonances, the so‐called quasi …

ZnO with various morphologies and contents was used to decorate reduced graphene oxide
(rGO) sheets via an easy one-step low-temperature chemical etching route to improve …

It is well known that the quasinormal modes (or resonant states) of photonic structures can
be associated with the poles of the scattering matrix of the system in the complex-frequency …

Tailoring nanoscale light concentration and electromagnetic near-field enhancement over a
broad spectral range is crucial for many photonics applications such as infrared …

Silver double nanorings with circular intra-nanogaps between two nanorings of different
diameters were synthesized without a linker molecule to confine an incident electromagnetic …

We study scattering phenomena such as the Kerker effect, superscattering, and scattering
dark states in a subwavelength atomic antenna consisting of atoms with only electric dipole …

All-optical operation holds promise as the future of computing technology, and key
components include miniaturized waveguides (WGs) and couplers that control narrow …

We demonstrate theoretically an extreme scattering nonreciprocity, namely nonreciprocal
transparency, in an asymmetric aggregate of deep-subwavelength gyrotropic trimer rods. By …

In this paper, engineering the optical characteristics of aluminum nanoring arrays has been
investigated with the aim of achieving a practical design approach to the realization of dual …

Plasmonic grating structures have been shown effective at increasing near-field optical
enhancement. A double-width plasmonic grating design is introduced, where each period …
