Abstract
A three-dimensional left-handed metamaterial having a completely new constitution, which functions as a three-dimensional electromagnetic wave propagation medium and in which an equivalent permittivity and a permeability of the medium simultaneously take negative values. The three-dimensional left-handed metamaterial is structured such that cubic unit cells 5 are disposed repeatedly in three orthogonal directions of a three-dimensional space, and includes: a first particle 1 constituted by a conductor and disposed in positions centering on respective vertices of the unit cell; a second particle 2 constituted by a conductor and disposed in positions centering on face center points, which are centers of respective faces of the unit cell; a first connecting portion constituted by a conductor, which connects the first particles to a center point of the unit cell; and a second connecting portion constituted by a conductor, which connects the second particles to the center point.
