Abstract :
This paper presents some recent advances in the electromagnetic modeling and design of substrate integrated waveguide (SIW) components. The modeling of losses in SIW structures is discussed in details, and a new formula for the calculation of the attenuation constant due to radiation loss is introduced. In addition, an efficient technique for the modeling of arbitrarily shaped SIW components is discussed: this technique is based on the Boundary Integral-Resonant Mode Expansion (BI-RME) method. The BI-RME method permits the direct derivation of parametric and multimodal equivalent circuit models of SIW discontinuities, which can be adopted in the fast design of SIW components and systems.
