Abstract :
We review the electromagnetic properties of artificial structures such as photonic band gap materials (Electromagnetic Band Gap at microwaves) and metamaterials with main emphasis on backward (left-handed) propagation media. We consider free space and guiding structures by showing how the interaction of the electromagnetic wave with periodic dielectric (PBGs) and double negative metallic structures (DNGs) yields a negative refractive index. Some of the potential applications in connection with negative index media are briefly discussed such as focusing for a flat lens and phase advance for a left handed transmission line.
