Efficient modelling of finite-size ungrounded PCBs with a full wave 3D moment-method analysis

摘要

A method in which 2D sheet-impedance elements are used to represent the finite-size dielectric substrate of an ungrounded PCB within a full wave 3D moment-method analysis (MoM) is presented. The use of these 2D elements significantly reduces both the core-memory demands and the CPU requirements of the MoM by an order of magnitude, with little compromise in accuracy.
