Abstract
Currently, aerosol is considered as the major route for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission. A safe sterilization method with an excellent penetration capability and ability to sterilize free spaces is urgently needed. Previously it has been experimentally demonstrated that microwave-based sterilization can effectively inactivate the H3N2 Influenza A virus through the structure-resonant energy transfer (SRET) effect with a radiation field intensity following the IEEE standard. In order to utilize the same mechanism to inactivate the SARS-CoV-2 virus, firstly, the structural resonant frequencies with electromagnetic (EM) waves have to be identified. In this paper we report our design and implementation of a spectrum measurement chip utilizing the coplanar waveguide with pre-printed mask. With the mask, the repeatability of the insertion loss measurement can be well-controlled. Our microwave absorption spectra results revealed that the coplanar-waveguide chip can identify the resonant microwave frequencies of difference viruses, including the SARS-CoV-2 viruses, highlighting the potential applications for not only the virus detection but also the safe and non-thermal sterilization of public spaces. During the presentation, we will also report the resonant EM wave frequencies of various corona viruses monitored by the aforementioned chip. Copyright © 2022 SPIE.
