Finite-Difference and Pseudospectral Time-Domain Methods Applied to Backward-Wave Metamaterials
Backward-wave (BW) materials that have simultaneously negative real parts of their electric permittivity and magnetic permeability can support waves where phase and power propagation occur in opposite directions. These materials were predicted to have many unusual electromagnetic properties, among them amplification of the near-field of a point source, which could lead to the perfect reconstruction of the source field in an image [J. Pendry, Phys. Rev. Lett. vol. 85, pg. 3966, 2000]. Often...[Show more]
