Development and application of physics-based compact models for high-impedance electromagnetic surfaces integrated in a power plane configuration

Abstract

Physics-based compact models for the unit cell of power planes with integrated high-impedance electromagnetic surfaces are developed and cascaded in a two-dimensional array to build full models for large and multi-layer power planes. The compact model offers a significant advantage to the FEM-based electromagnetic simulation as it reduces the analysis time of a typical 10 cm/spl times/10 cm power plane from 40 hours to less than 10 seconds. The proposed compact model is also used to explore the noise mitigation at different locations of the power plane and in combination with RC decoupling for broadband noise mitigation.
