The invention discloses an open-area high-frequency electromagnetic virus killing device and method based on an electromagnetic metamaterial. The device comprises a magnetron, a transmitting antenna,an electromagnetic metamaterial cavity, an air suction device, a power supply and a control system, the transmitting antenna is positioned between the magnetron and the electromagnetic metamaterial cavity; the transmitting antenna is connected with the magnetron; high-frequency electromagnetic waves emitted by the magnetron are transmitted to the electromagnetic metamaterial cavity through the transmitting antenna; the power supply and control system is connected with a power supply interface of the magnetron, the electromagnetic metamaterial cavity is of a porous reticular structure, the airsuction device is communicated with the electromagnetic metamaterial cavity, and the device and the method can vaporize droplets in an open area of a larger space.

Open-area high-frequency electromagnetic virus killing device and method based on electromagnetic metamaterial

A ventilation passage arranged with a microwave active antenna device is provided, which relates to a ventilation passage used for central air-conditioning. Aims at that the ventilation passage of the current central air-conditioning kills the virus in the flowing air by filtering, spraying medicine liquid, ultraviolet lamp shining and other ways, which has the defects of complication and inconvenient operation, low efficiency and high cost, and provides a ventilation passage which adopts microwave electrical technology disinfection and is arranged with a microwave active antenna device. The adopted technological proposal is that a microwave antenna output end 1 is arranged on the wall of a ventilation passage 2.
