1. A planar metamaterial comprising:

  • two substantially orthogonal, coplanar sets of transmission lines, said transmission lines being spaced with a periodicity, loaded with capacitors with said periodicity, and shunted with inductors with said periodicity such that for an electromagnetic wave, having a wavelength greater than said periodicity and traveling along the plane of said transmission lines, the effective permeability and permittivity of said metamaterial are simultaneously negative.
