We explore the concept of spoof surface plasmon polaritons (SSPPs) as a means to confine plasmons on the surface of a tiny metallic structure. We focus on introducing an efficient transition design that confines the SSPP wave along a corrugated metallic strip with metal acting as a ground material. To achieve this, a unique unit cell specifically designed for waveguiding purposes was analyzed. The dispersion characteristics of this design were presented, demonstrating its potential for SSPP waveguiding applications. By varying the groove height from h1 to h7 (ranging from 0.5 to 3.5 mm), the SSPP waveguide was developed and analyzed its spectral characteristics through corresponding S parameters. Furthermore, the effects of altering the corrugated groove width from 1 to 2 mm was investigated. This variation is shown to have a linear impact on the gain, with a maximum gain of 7.71 dBi observed. [ABSTRACT FROM AUTHOR] |
