  • Publication number: 20250072435
    Abstract: Methods and apparatus for inducing unconsciousness by warming of the brain of an animal by applying microwave radiation through an applicator are described. An electromagnetic flux concentrator comprises a tubular section of reducing internal cross-sectional area and at least one ridge internally thereof extending longitudinally. The applicator is pre-tuned by directing low-power microwave radiation therethrough to a load that approximates the properties of the animal's head, and adjusting the impedance of the applicator to optimize the impedance match. A compensator associated with the waveguide compensates for changes in detected reflected power.
    Type: Application
