Abstract
Provided are an artificial atom of a metamaterial by coiling up space, a metamaterial including the artificial element, and a device including the metamaterial. The artificial atom of the metamaterial by coiling up space includes a first coiling unit that coils up a first space and a second coiling unit that coils up a second space and that is connected with the first coiling unit.
Claims29
An artificial atom forming a metamaterial, comprising:
- a first coiling unit comprising first channels that are parallel to each other and arranged in a first direction, one of the first channels being an output channel which outputs a wave propagating through the first channels to a point;
- and
- a second coiling unit connected with the first coiling unit and comprising second channels that are parallel to each other and arranged in a second direction different from the first direction, one of the second channels being an input channel which inputs a wave propagating through the second channels from the point.
An artificial atom forming a metamaterial, the artificial atom comprising:
- an inlet configured to receive an incident wave;
- an outlet configured to output the incident wave;
- and
- a coiling unit configured to propagate the incident wave along a zigzag path from the inlet toward the outlet,
- wherein a refractive index of the artificial atom is proportional to a length of the zigzag path.
An artificial atom forming a metamaterial comprising:
- an inlet configured to receive an incident wave;
- an outlet configured to output the wave;
- and
- a coiling unit that is connected from the inlet to the outlet and configured to propagate the wave along a path from the inlet to the outlet,
- wherein a length of the path in the coiling unit is longer than a straight-line distance between the inlet and the outlet, and
- wherein a refractive index of the artificial atom is proportional to the length of the path.
