“…In a PEEC circuit network, (15) can be rewritten in a compact matrix form as With the definition of partial coefficient of potential in (17), the electric scalar potential Φ(ω) defined by (3) is related to the charges located on the meshed surface patches as (18).…”

“…After the initial node placement, surfaces are meshed using quadrilateral elements from which coefficients of potentials are calculated using (17). Depending on the boundaries of the surface mesh, volume cells are created as hexahedral cells from which partial inductances and resistances are calculated using (13) and (14), respectively [18]. It facilitates the partial elements calculation using such quadrilateral and hexahedral elements in the mesh [25,26].…”

“…The majority of the PEEC implementations mesh surfaces using quadrilateral elements and volume cells are created as hexahedral cells. The basic rule of thumb when carrying out discretization for PEEC modeling is to use a fixed number of cells per shortest wavelength λ min corresponding to the highest frequency of interest [18]. Following this conventional solution, excessive number of unknowns and subdivisions will be introduced, especially for large structures at high frequencies.…”

Abstract-The wire-ground electromagnetic coupling structures are quite common in avionics system electromagnetic compatibility (EMC) analysis. The increasing complexities of physical structures make electromagnetic modeling an increasingly tough task, and computational efficiency is desirable. In this paper, a novel selective mesh approach is presented for partial element equivalent circuit (PEEC) modeling where intense coupling parts are meshed while the remaining parts are eliminated. With the proposed approach, the meshed ground plane is dependent on the length and height of the above wires. Relevant compact formulae for determining mesh boundaries are deduced, and a procedure of general mesh generation is also given. A numerical example is presented, and a validation check is accomplished, showing that the approach leads to a significant reduction in unknowns and thus computation time and consumed memories, while preserving the sufficient precision. This approach is especially useful for modeling the electromagnetic coupling of wires and reference ground, and it may also be beneficial for other equivalent circuit modeling techniques.

This paper proposes a novel electrical characterization approach for a high-performance package system using an improved Partial Element Equivalent Circuit (PEEC). As the effect of interconnects becomes a pivotal factor for the performance of high-speed electronic systems, there is a great demand for an accurate equivalent model for interconnects. In particular, an equivalent model of interconnects is established in this paper for the Fine-Pitch Ball Grid Array (FBGA) package using the improved PEEC method. Based on the equivalent model, electrical characteristics are analyzed; furthermore, these are verified through the measurement results of a Vector Network Analyzer (VNA).

“…However, as with other integral methods, it can suffer from numerical instability [2]. Also, retardation effects become significant when analysing structures whose size is significant compared with the wavelength of interest, since the time taken for the electromagnetic radiation to propagate through the structure has to be taken into account.…”
