Propagation characteristics including complex propagation constants and effective wave impedance of pins-loaded microstrip line under operation of the first higher-order EH1 mode are numerically de-embedded. Although numerous methods have studied the features of EH1-mode, full-wave numerical extraction of the entire propagation characteristics of the pins-loaded EH1-mode microstrip line is for the...
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 paper, a numerical short-open calibration (SOC) method is presented to numerically deembed the complex propagation constant of half-mode substrate integrated waveguide (HMSIW). After three distinctive equivalent circuit networks are described for SOC deembedding procedures, the propagation characteristics of HMSIW can be extracted. The numerical stability and convergence are illustrated. Two...
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...
This paper aims to give unified characterization of coplanar-waveguide-based 1D electromagnetic-bandgap (EBG) and metamaterial in terms of two fundamental per-unit-length (PUL) transmission parameters, i.e., characteristic impedance and propagation constant. In analysis, a full-wave self-calibrated method of moments (MoM) is applied to de-embedding these two PUL parameters from simulation of two-port...
This paper aims to give a unified characterization of various periodically loaded transmission line media/materials with infinite extent on coplanar waveguide (CPW) in terms of two fundamental per-unit-length (PUL) transmission parameters, i.e., frequency-dispersive/complex characteristic impedance and propagation constant. Regardless of varied periodic loading elements, a self-calibrated method of...
Transmission line metamaterials on CPW with unsymmetrical unit cells, loaded by series- C and shunt-L elements, are studied to demonstrate the distinctive characteristics of incident and reflected guided-waves. Two sets of per-unit-length transmission parameters, i.e., propagation constant and Bloch-wave impedance, are numerically extracted using our self-calibrated method of moments and they are...
