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.

高折射率粒子中的光学类LC共振

金属电路中发生的电 LC 谐振控制着自由电子或电信号的运动。在本文中，研究了高折射率粒子（HIP）中的光学类液晶共振或介电液晶共振，其中涉及束缚电子和光场。谐振效应主要由电感和电容的光学类似物决定，这可以根据粒子附近的电磁能来确定。具有等效参数的介电光路的观点有助于理解介电共振效应。该结果还为研究HIPs的光学性质提供了一种方法。
