In this paper, a corrugated substrate integrated waveguide (CSIW) with no metallic vias is proposed, and its propagation characteristics are investigated via our numerical SOC de-embedding method. In our analysis, dominant operating modes in this CSIW at different frequencies are extensively discussed. In final, its complex propagation constant, i.e., phase and attenuation constants, is derived to...
In this letter, a numerical short-open-calibration (SOC) technique is developed to be integrated with the electromagnetic (EM) software for direct de-embedding of propagation constant of substrate integrated waveguide (SIW). The two calibration standards, i.e., short- and open-end circuits can be perfectly built up by means of perfectly electric and magnetic walls in numerical algorithm. After three...
In this letter, a numerical short-open-calibration (SOC) technique is developed to be directly integrated with the commercial electromagnetic software for accurate extraction of propagation constant of substrate integrated waveguide (SIW) with longitudinally periodic metallic posts. Short- and open-end circuits can be exactly realized by means of electric and magnetic wall in software respectively...
