Abstract
Electric LC resonances, occurring in metallic circuits, govern the motion of free electrons or electric signals. In this paper, optical LC-like resonances in high-index particles (HIPs) or dielectric LC resonances have been studied, which involve bounded electrons and optical fields instead. The resonance effect is dominated by optical analogues of inductance and capacitance, which can be determined according to the electromagnetic energy bounded near the particle. The viewpoint of dielectric optical circuit with equivalent parameters facilitates the understanding of dielectric resonance effect. The result also provides a method for studying the optical properties of the HIPs.
期刊介绍：
This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
