标题： An indirect correlation of dielectric properties using optical trapping and dielectric resonance in two different frequency regimes

摘要： 介电常数，$\varepsilon_r$，通常使用普通的LCR表限制在亚GHz范围内。 在GHz范围内，可以使用矢量网络分析仪和测量夹具（波导）来测量$\varepsilon_r$，这些波导针对不同的频率范围有所不同。 因此，为了测量整个频率范围内的er，需要多个组件，这是一个极其昂贵的实验。 然而，对于诸如介电谐振器天线等应用，需要知道er和介电损耗以估算谐振频率。 本文提出了一种间接方法，通过在光频范围内横向错位双光纤光学捕获来找到er，从而大致估计{\epsilon }r，并理解这两个频率响应区域之间的相关性。 显示英文摘要

摘要： Dielectric permittivity, $\varepsilon_r$, of materials are often limited to a sub-GHz range using normal LCR meters. In the GHz range the $\varepsilon_r$ can be measured using Vector Network Analyzers and measurement jigs (waveguides) which are specific for different frequency regimes. Hence, to measure er for the entire frequency range one needs several components and is an extremely costly experiment. However, for applications such as Dielectric Resonator Antennas one need to know the er and the dielectric loss to estimate the resonant frequency. An indirect method is proposed in this letter to find the er from Transversely Misaligned Dual-Fiber Optical Trapping at the optical frequency range to approximately estimate {\epsilon}r and thereby understand the correlation between these two regimes of frequency responses.
