    Abstract: Embodiments of the invention include electromagnetic band gap (EBG) structures having undulating branches to tune the resulting stopband. A periodically patterned structure of conductive patches are interconnected by the undulating branches. Physical parameters of the undulating branches, such as the number of undulations or “turns” per branch, may be selected to tune the stopband in an effort to achieve a target stopband. Accordingly, embodiments of the invention also include methods of designing and manufacturing an EBG structure using undulating branches.
