Abstract :
A rectangular waveguide (RW) to domino plas-monic waveguide (DPW) converter in X-band (8.2-12.4GHz), which is based on the high-efficiency conversion between guided waves and domino plasmon polaritons (DPPs), is proposed in this work. A matching transition composed by gradient domino arrays and flaring upper wall to match the wave number and impedance between the RW and DPW has been presented and designed. Simulated results on the S-parameters and near-field distributions show excellent transmission performance between the RW and DPW in the X-band. The proposed plasmonic metamaterial can find potential applications in advanced plasmonic integrated devices and circuits in the microwave and THz frequencies.
