The Contour Integral Method (CIM) is a numerically efficient modeling technique for planar or infinitely extended two-dimensional (2-D) structures. In the optical regime, the CIM has already been adapted and applied for the modeling of TM0z-mode scattering in photonic crystals. In this work the dual case of TE0z-mode scattering is addressed. Making use of the duality principle, expressions for the...
In this paper, the mode conversion in differential links of printed circuit boards and package structures is investigated, taking into account the ground via arrangement and trace length mismatch. The links are modeled using physics-based via and trace models that have been validated previously with full-wave methods and measurements. The very good numerical efficiency of these models allows simulations...
In this paper, the simulation of via interconnects in multilayered printed circuit boards (PCBs) and packages combining physics-based via models and microwave network theory will be discussed. The description of the via in terms of network parameters, partitioning of the system, and combination of partial results will be addressed. Two alternatives to combine the results are compared, namely multiplication...
