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.

一些研究集中于利用微波照射来灭活生物微生物，例如病毒，并引入了一些设备。本文代表了通过制造一种新的但非常简单的电磁暴露测试装置来灭活病原体的可行性研究。该装置的优点是可以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 GHz。测试装置中的辐射单元由两个圆形平行板组成，可以被视为平行平面径向传输线。该装置中嵌入了五个等间距的孔，用于插入含有样品的试管。该研究还测量了试管液体内部的场分布。结果表明，在不插入试管的情况下，TEM 波在辐射单元中传播，而插入试管时会在试管内产生驻波。该装置可以通过 0.5 瓦的输入功率在液体内产生超过 100 V/m 的电场水平，这比使用露天方法要好得多。
