  • Microwave heating method, microwave heating apparatus, and chemical reaction method
    Patent number: 11883789
    Abstract: A microwave heating method using a microwave, including: controlling a frequency of the microwave, to form a single-mode standing wave; disposing an object to be heated in a magnetic field region where a strength of a magnetic field formed by the single-mode standing wave is uniform and maximum; and heating the object to be heated by magnetic heat generation by magnetic loss caused by an action of the magnetic field of the magnetic field region, and/or induction heating by an induced current generated in the object to be heated due to the magnetic field of the magnetic field region.
    Type: Grant
    Filed: February 7, 2019
    Date of Patent: January 30, 2024
    Assignee: NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGY
    Inventors: Yuichi Watanabe, Sei Uemura, Masateru Nishioka, Masato Miyakawa, Takashi Nakamura
  • MICROWAVE PROCESSING APPARATUS, MICROWAVE PROCESSING METHOD, AND CHEMICAL REACTION METHOD
    Publication number: 20210392723
    Abstract: The present invention provides a microwave processing apparatus, including: a cavity resonator having a cavity that forms a standing wave of a microwave; and a dielectric portion disposed occupying at least one-fifth of a volume of the cavity, in the cavity, in which an object to be processed being at through at least one end side of the cavity resonator is disposed in the cavity resonator, and the object to be processed is processed by the standing wave.
