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.
期刊介绍:
Transactions of Electrical Engineering is to foster the growth of scientific research in all branches of electrical engineering and its related grounds and to provide a medium by means of which the fruits of these researches may be brought to the attentionof the world’s scientific communities.
The journal has the focus on the frontier topics in the theoretical, mathematical, numerical, experimental and scientific developments in electrical engineering as well
as applications of established techniques to new domains in various electical engineering disciplines such as:
Bio electric, Bio mechanics, Bio instrument, Microwaves, Wave Propagation, Communication Theory, Channel Estimation, radar & sonar system, Signal Processing, image processing, Artificial Neural Networks, Data Mining and Machine Learning, Fuzzy Logic and Systems, Fuzzy Control, Optimal & Robust ControlNavigation & Estimation Theory, Power Electronics & Drives, Power Generation & Management The editors will welcome papers from all professors and researchers from universities, research centers,
organizations, companies and industries from all over the world in the hope that this will advance the scientific standards of the journal and provide a channel of communication between Iranian Scholars and their colleague in other parts of the world.
