论文摘要
与单个频率介电常数研究相比，在频率范围内的复杂液体介电常数的准确测量提供了有关液体性能的重要信息。提出，开发和演示基于带有微流体芯片的单个石英窃窃私语模式（WGM）谐振器的多频微波表征技术。该技术允许在30-40 GHz频率范围内以六个谐振频率测量少量液体的复杂介电常数。校准是通过模拟测量单元和绘制所有六个研究频率的校准命名图表来执行的。新方法应用于水溶液中L-赖氨酸的复杂介电常数的研究。结果开辟了可能在几个频率下研究生物液体的复杂介电常数的可能性，并使用单个高Q WGM谐振器的准光学性质在一定频率范围内进一步开发了小液体体积的微波介电测定法。
The accurate measurement of complex liquid permittivity in a frequency range provides important information on liquid properties in comparison to single frequency permittivity investigations. The multifrequency microwave characterization technique based on a single quartz whispering-gallery-mode (WGM) resonator with a microfluidic chip are proposed, developed, and demonstrated. This technique allows the complex permittivity of small volumes of liquid to be measured at six resonant frequencies in the 30-40 GHz frequency range. The calibration is performed by simulating the measurement cell and by plotting the calibration nomogram charts for all six investigated frequencies. The novel approach is applied in studies of the complex permittivity of the L-lysine in water solutions. The results open up possibilities to investigate the complex permittivity of biological liquids at several frequencies and to further develop the microwave dielectrometry of small liquid volumes in a certain frequency range using the quasi-optical nature of a single high-Q WGM resonator.
