Claim 0:
1. A modulatable infrared emitter, comprising
a heating element;
a planar base element made of a conductive material;
a dielectric interlayer;
a planar cover element made of a conductive material; and
an actuator,
wherein the cover element is a structured metamaterial with periodically arranged unit cells and the actuator is configured for relative movement of the cover element and the base element between a first and second position in order to modulate the intensity of the emission of the infrared emitter,
wherein the relative movement comprises a horizontal translational movement of the cover element and/or base element orthogonal to the emission direction of the infrared emitter, which changes the degree of overlap between the cover element and the base element.
