Remote Destruction & Sterilization of the Coronavirus by RF/Microwave Wireless Power Transmission

The proposed PhD research plan is to develop further a new methodology that can help combat the COVID-19 pandemic by remote microwave sterilization of surfaces and air particles using antenna radiation and wireless power transmission.

The concept basically works like a conventional microwave oven where materials/surfaces, etc. can be sterilized by radiating safe RF/microwave energy.

However, the new idea is to make this process remote, such that an operator, or self-managed system, could sterilize a room or ambulance (for example) with a simple hand-held device or air-conditioner unit, and whilst not even touching the infected surface, air particulates, or a handling of any harsh chemical cleaner. The methodology basically uses a liquid film layer to deactivate the corona virus and other pathogens by thermal heating.

To transfer the energy or power wirelessly, the system is constituted by electronically steerable RF antennas and beam focusing, controlled by the supporting electronics. The process can also include a visual colour indicator for the operator to know when the temperature required for coronavirus deactivation has been achieved.


The motivation of the PhD research will be to continue these important efforts.
