Reconfigurable Microwave Components Using Glide-symmetric Pin-loaded Parallel Plates

Glide-symmetric structures have recently gained a lot of interest in the design of electromagnetic bandgap materials due to their high attenuation in the stopband region and for their capability to support an almost dispersionless wave propagation. In this paper, we propose a reconfigurable waveguide using a glide-symmetric structure with pins. We show how the wave propagation in this waveguide can be enabled or suppressed by a mere adjustment of the displacement between the two metallic plates of the waveguide. In addition, we demonstrate how this structure can be used to design a phase shifter.
