Abstract: An infrared heater includes a heater body and a casing. The heater body includes a heating element and a metamaterial structure capable of emitting infrared radiation having a peak wavelength of a non-Planck distribution when thermal energy is supplied from the heating element. The casing has an interior space in which the heater body is disposed and whose pressure is reducible. In addition, the casing includes an infrared radiation transmitting portion capable of transmitting the infrared radiation emitted by the metamaterial structure to an outside of the casing.

Abstract: An infrared radiation device includes a body including a heat generating part and first and second metamaterial structures that are capable of radiating infrared rays having a peak wavelength of a non-Planck distribution upon receipt of thermal energy from the heat generating part. The first metamaterial structure is disposed on a first surface side of the heat generating part, and the second metamaterial structure is disposed on a second surface side opposite to the first surface side of the heat generating part.

Abstract: An infrared processing device includes an infrared heater including a heating body and a metamaterial structure capable of, when thermal energy is input from the heating body, radiating infrared rays which have a maximum peak of a non-Planck distribution and whose maximum peak has a peak wavelength of 2 μm or more and 7 μm or less; an inner tube that surrounds the infrared heater, contains at least one of a fluorine-based material having a C—F bond and calcium fluoride, and transmits infrared rays of the peak wavelength; and an outer tube that surrounds the inner tube and forms, between the inner tube and the outer tube, an object channel through which a processing object is allowed to flow.

Abstract: A method for producing a reaction product, with which the reaction product is obtained from a starting material through a particular organic synthesis reaction, the method includes (a) a step of setting a target wavelength to a peak wavelength of a reaction region involved in the organic synthesis reaction in an infrared absorption spectrum of the starting material; (b) a step of preparing an infrared heater that emits an infrared ray having a peak at the target wavelength from a structure constituted by a metal pattern, a dielectric layer, and a metal substrate stacked in this order from an outer side toward an inner side; and (c) a step of obtaining the reaction product by allowing the organic synthesis reaction to proceed while the infrared ray having a peak at the target wavelength is being applied to the starting material from the infrared heater.

Abstract: A method of drying a coating film formed on a surface of a PET film includes radiating an infrared ray having a dominant wavelength of 3.5 μm or less from an infrared heater onto a PET film on whose surface the coating film containing water or an organic solvent having an absorption spectrum of 3.5 μm or less has been formed, where the infrared heater has a structure such that an outer circumference of a filament is covered with a protection tube, and a partition wall for forming a flow passageway of a cooling fluid that restrains rise in temperature of a heater surface is provided in a space surrounding this protection tube, and bringing cooling air into contact with the surface of the PET film/coating film has been formed, so as to dry the PET film at a temperature lower than a glass transition point of the PET film.
