Abstract

A metamaterial is configured by arranging at least one element on a planar conductor plate, where the at least one element has a first conductor portion arranged a predetermined distance away from the conductor plate in a two-dimensional plane that includes the conductor plate, and a second conductor portion arranged so as to connect the conductor plate and the first conductor portion.

First claim

What is claimed is:

1. A metamaterial configured by arranging at least one element on a planar conductor plate,
the at least one element having:
a first conductor portion arranged a predetermined distance away from the conductor plate in a two-dimensional plane that includes the conductor plate; and
a second conductor portion arranged so as to connect the conductor plate and the first conductor portion,
wherein the element further has a third conductor portion that is arranged so as to be connected to an end portion of the first conductor portion, is approximately perpendicular to a straight-line shaped side of the conductor plate, and is straight-line shaped and extends toward the straight-line shaped side, and
wherein the element further has a fourth conductor portion that is arranged so as to be connected to an end portion of the third conductor portion, is approximately parallel to a straight-line shaped side of the conductor plate, and is straight-line shaped and extends toward the second conductor portion.

2. The metamaterial according to claim 1 , wherein in the element, the first conductor portion is arranged approximately parallel to a straight-line shaped side of the conductor plate, and the second conductor portion is arranged approximately perpendicular to a straight-line shaped side of the conductor plate.

3. The metamaterial according to claim 1 , wherein in the element, the first conductor portion is straight-line shaped, and the straight-line shaped side of the conductor plate and the first conductor portion are approximately parallel.

4. The metamaterial according to claim 1 , wherein in the element, the second conductor portion is meander-line shaped.

5. The metamaterial according to claim 1 , wherein in the element, the second conductor portion is spiral shaped.

6. The metamaterial according to claim 1 , wherein in the element, the line widths of the first conductor portion and the second conductor portion are the same.

7. The metamaterial according to claim 1 , wherein in the element, the line widths of the first conductor portion and the second conductor portion are different.

8. The metamaterial according to claim 1 , wherein a plurality of the elements are arranged in a line along a straight-line shaped side of the conductor plate.

9. The metamaterial according to claim 1 , wherein a plurality of the elements are arranged in a line extending in a direction perpendicular to the two-dimensional plane that includes the conductor plate, along a side surface of the conductor plate.

10. The metamaterial according to claim 1 ,
wherein the conductor plate has a plurality of sides, and
a plurality of the elements are arranged in a line extending along each of the plurality of sides of the conductor plate.

11. The metamaterial according to claim 1 ,
wherein the conductor plate has a plurality of sides, and
a plurality of the elements are arranged in a line extending in a direction perpendicular to the two-dimensional plane that includes the conductor plate, along each of the plurality of side surfaces of the conductor plate.

12. The metamaterial according to claim 1 , wherein the metamaterial has a characteristic of an antenna, an EBG structure, or a magnetic wall.
