  • Abstract
    A reconfigurable low-pass filter that uses reversibly actuated liquid metal as the tuning mechanism is demonstrated. Reversible tuning of up to eight cutoff frequencies is achieved by filling and evacuating defected ground structure lattices with Galinstan liquid metal. Measurements of four of the cutoff frequencies show a 59% tuning range.
