Abstract

The invention relates to a modulatable infrared emitter comprising a heating element, a planar base element, a dielectric interlayer, and a planar cover element which is a structured metamaterial, and an actuator, wherein the actuator is configured for a relative movement of the cover element and the base element between a first and a second position in order to modulate the intensity of the emission of the infrared emitter. The invention further relates to production methods for the infrared emitter, methods for the modulated emission of infrared red radiation by means of the infrared emitter, and preferred uses of the infrared emitter. A system comprising the infrared emitter and a control device for regulating the actuator are also preferably the subject matter of the invention.
