Abstract :
The present work focuses on the study of bandgaps of soft surfaces in the form of metal strips printed on grounded dielectric slabs when the strips are provided with a metal connection to the ground plane. We can refer to such a structure as a modern realization of cavity loaded corrugations. In particular, the dispersion properties of the surface wave are investigated in order to find the bandgap.
