Claims8
An electromagnetic wave heating device comprising:
- a conductive housing including a first shield being conductive and having an opening, and a second shield that has a conductive mesh with a shape in which a plurality of mesh cells, each enclosed by straight sides of equal length each having a line width being equal to or less than 10 μm, are arranged in an array, and is provided at the opening of the first shield, the conductive mesh being electrically connected to the first shield to form an electrically closed space by the first shield and the second shield;
- an electromagnetic wave generator to generate an electromagnetic wave;
- and
- an electromagnetic wave emitter that is housed inside the conductive housing, and emits the electromagnetic wave from the electromagnetic wave generator into a space of the conductive housing,
- wherein electrical connection between the first shield and the conductive mesh in the second shield is established at points of contact or capacitive coupling between the first shield and the conductive mesh of the second shield arranged with an interval which is equal to or less than 1/10 of a wavelength of the electromagnetic wave generated by the electromagnetic wave generator.
