Abstract
In this talk, the potential of controlling the electromagnetic propagation by periodically-textured surfaces is reviewed. It is shown that backward-wave- and slow-wave-propagation, superluminal, effective negative refractive index and highly-confined complex surface waves are obtained with these metallic surfaces. The role of periodicity, complex surface waves and resonant-electric-coupling in all these phenomena is emphasized and compared against equivalent circuit models. The explanation of the underlying physics is combined with exemplary applications focused on the millimetre- and submillimetre-wave band.
