Abstract
The propagation in and scattering from Planar metamaterials that exhibit a zero index of refraction within a specified frequency band, were investigated. Finite difference time domain (FDTD) simulator was used to treat the corresponding one- and two-dimensional scattering problems. Since the matched zero-index slab transformed the cylindrical waves generated by an internal line source into planar wavefronts, it was suggested that such a slab would do the same to the fields radiated by an external line source. The results show that in steady state, the fields in the matched zero-index medium are static in character but the underlying dynamics are that of propagating transverse waves.
