Abstract

Several studies have focused on the inactivation of biological microorganisms, such as viruses, using microwave exposure and have introduced some apparatuses. This paper represents a feasibility study of the inactivation of pathogens by fabricating a new, but very simple electromagnetic exposure test setup. The setup has the advantage of having uniform electric field radiation on multiple test tubes simultaneously. The test setup operates from 8 to 9 GHz. The radiation unit in the test setup consists of two circular parallel plates and can be considered a parallel-plane radial transmission line. Five equispaced holes are embedded in the setup to insert test tubes containing samples. The study also takes the distribution of the field inside the liquids of the test tubes. The results demonstrate that without inserting the test tubes, the TEM wave propagates in the radiation unit while inserting the test tubes creates a standing wave inside the test tubes. The setup can create E-field levels of more than 100 V/m from 0.5 Watts input power inside the liquid which is much better than using open-air methods.

微波照射致病样品的新装置
一些研究侧重于利用微波照射灭活病毒等生物微生物,并介绍了一些仪器。本文通过制造一种新型但非常简单的电磁曝露试验装置,对病原体灭活进行了可行性研究。该装置的优点是可同时对多个试管进行均匀的电场辐射。测试装置的工作频率为 8 至 9 千兆赫。测试装置中的辐射单元由两个圆形平行板组成,可视为平行面径向传输线。测试装置上有五个等距孔,用于插入装有样品的试管。研究还对试管液体内部的场分布进行了分析。结果表明,在不插入试管的情况下,TEM 波在辐射单元中传播,而插入试管后,试管内会产生驻波。该装置可以在液体内部以 0.5 瓦特的输入功率产生超过 100 伏特/米的电场水平,这比使用露天方法要好得多。
