摘要

研究了微波范围内电磁波在中心有低损耗介质棒、周围有高损耗液体的双层圆形金属波导中的传播。观测了电磁波与不同径向指数的相互作用。我们已经检测到，由于介质损耗高，这种波导结构没有固定的截止频率值。我们提出了不同水溶液(如液体食品(葡萄酒/果汁)成分)的复合介电常数的实验测量，以及尿素-水溶液与脲酶的时间相互作用，可以在微生物学研究中找到应用。该结构可作为小体积高损耗液体复介电常数的测量单元，在厘米至毫米波段的宽微波范围内测量。

High Loss Liquid in Layered Waveguide at Microwaves and Applications

The propagation of electromagnetic waves in a circular two-layer metal waveguide with a central low loss dielectric rod surrounded by high loss liquid in the microwave range has been studied. The interaction of the electromagnetic waves with different radial indices has been observed. We have detected owing to a high loss medium, such a waveguide structure does not have a fixed value of cutoff frequencies. We have presented experimental complex permittivity measurement of different water solutions such as liquids food (grape wines/juices) components and also the time interaction of urea-water solution with urease that can find the application in microbiology research. The proposed structure can be applied as a measuring cell for the determination of the complex permittivity of high loss liquids in small volume in wide microwave range from centimeter to millimeter wavelengths.
