Switchable Bandpass/Bandstop Filter Using Liquid Metal Alloy as Fluidic Switch [PDF]
Sensors, 2019 In this paper, we propose a switchable band-pass/band-stop filter using liquid metal alloy as a fluidic switch. The filter is designed based on the Chebyshev response and implemented using a three-stage quarter-wavelength resonant structure.
