Metamaterial
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.
