Claim:
A two-dimensional left-handed metamaterial in which unit structures are disposed regularly on a plane, characterized in that each of said unit structures comprises: a columnar first prism, a central axis of which is oriented perpendicularly to said plane; a columnar second prism that has a central axis in an identical direction to said first prism and is disposed at a different location from said first prism in a central axis direction; and a connecting body for electrically connecting said first prism and said second prism to each other, wherein said first prism and said second prism are formed such that a cross-section thereof perpendicular to said central axis takes a regular polygonal shape; wherein said first prism, said second prism and said connecting body are electrical conductors; wherein said unit structures are disposed in identical positions in a perpendicular direction to said plane and so as not to contact another unit structure.
