Abstract: This work aims at investigating a parity time-reversal duality (PTD) symmetric bifilar-line waveguide structure constituted by a pair of two parallel-plate waveguides with complementary ...
Abstract: This article presents a new type of microwave-induced atmospheric-pressure low-temperature dielectric barrier discharge source, based on the principle of parallel plate transmission lines ...
