Equivalent circuit model analysis of reconfigurable self-resonant structures

This work presents an analysis of a reconfigurable self-resonant structure using an equivalent circuit model. Reconfiguring the electrical length of the structure results in uniquely identifiable changes to its forward and reflected frequency response. Equivalent circuit models are known to reduce computational time drastically and to provide an insight into the physics of the electromagnetic problem. Equivalent circuit parameters have been calculated for different states of the self-resonant structure. The responses of these equivalent circuits are compared to a full-wave simulation with very good agreement.
