An adaptive SIW filter using vertically-orientated fluidic material perturbations

This paper examines the frequency reconfiguration of an SIW bandpass filter for frequency-agile operations. Dispersions of dielectric nanoparticles are used as vertically aligned fluidic material perturbations in these devices to provide electromagnetic agility for reconfiguration. Analytical modeling, simulated, and measured data for a single-pole X-band bandpass SIW filter.
