Remote Destruction of the Coronavirus by Dual-Polarized Wireless Power Transmission

Abstract

This paper proposes a remote sterilization technique through microwave radiation. The innovative approach requires the heating of a liquid water film layer, which can be sprayed onto the area of interest. Applications include the deactivation of the coronavirus and other pathogens by physically increasing the liquid film temperature achieving thermal sterilization. The proposed technique can be implemented by various antenna systems and retrodirective arrays. In this study, a dual-polarized antenna array is adopted and designed to increase the transmitted power levels without physically including more antenna elements. As reported in the paper, this dual-polarized approach has the benefit of reduced sterilization time when compared to a single-polarization system having the same number of antenna elements.
