To kill virus in public space for epidemic prevention, chemical inactivation is currently treated as the most effective way. However strong chemical might affect the public health, while its coverage and penetration are both limited so as to be treated as a thorough and complete disinfection method. A sterilization method with a better penetration capability and space coverage is under urgent demand. Our previous study showed that spherical virus will resonate with microwave at the confined-acoustic dipolar mode of the same frequency. Our recent study further indicated that this structure-resonant energy transfer (SRET) effect from microwaves to virus can be efficient enough so that influenza virus in respiratory droplet or aerosol can be inactivated with reasonable microwave power density safe for the open public. With microwave’s high penetration and high spatial coverage characteristics, our previous results provide an alternative toward establishing a new microwave-based epidemic prevention strategy in open public for SARS-Cov-2 transmission. In this program, we aim to establish a guideline for efficient pathway control of SARS-CoV-2 transmission with low dosage microwave irradiation. To inactivate SARS-CoV-2 using SRET with microwave, the following technical steps are planned under this program 1.The dipolar mode frequencies of SARS-Cov-2 will be determined by using microwave spectrum analyzer through resonance absorption in the lab. 2.At or around the dipolar mode frequency, the microwave-dosage dependent inactivation efficiency will be measured in the lab. Besides these above major items, the following issues will be explored in this program: 1.To confirm and to test the above conclusion, the follow-up plans to test the virus disinfection method in open space should be planned through international collaborations. 2.We will initiate the design and implementation of compact and low-cost microwave sanitizers for various application fields through domestic and international collaboration. 3.We will further explore the possibility to extend our result for early detection and therapy of COVID-19.新冠病毒結構共振能量轉移微波共振吸收消滅病毒病毒檢測SARS-Cov-2Structure resonance energy transfermicrowave resonance absorptionvirus inactivationvirus detection以低劑量微波輻射消滅病毒
