Dispersion analysis of a reconfigurable unit cell in a one dimensional periodic architecture

Dispersion analysis of a unit cell in a one dimensional microstrip based periodic arrangement is studied. Topology of the unit cell allows it to reconfigure the internal design using active devices into two different states. Active devices are modeled using perfect electric conductors in this study, which take in to account the different state of the switches. The obtained dispersion diagram provides useful insight into bounded and unbounded modes inside the unit cell in both states. The modal analysis reveals the possible applications for this potentially reconfigurable unit cell based periodic arrangement in microwave filters and leaky wave antennas.
