Surface-wave suppression of resonance-type periodic structures

Periodic structures of the resonance type are investigated with a focus on the utilization of structure dispersion to achieve a wideband operation for the surface-wave suppression. Both approximate and exact formulations are presented to illustrate wave processes involved in the resonant structure and to develop useful criteria for design purpose. In addition, experiments are performed to verify the phenomena with stopband and leakage associated with the resonance-type periodic structures.
