Physical interpretation of radiation and transfer characterization based on the PEEC method

The characterization of power radiation and coupling has been an important research subject. The partial element equivalent circuit method (PEEC) is a powerful tool in bridging the electromagnetic modeling together with a circuit solver. Even though PEEC was a convenient tool for many quasi-static applications, in this paper, we propose a new approach for PEEC to calculate the radiated and coupled power from the distributive point of view. Formulations for both radiated and transferred powers are proposed based on a full wave PEEC model. Distributive power can be evaluated with negligible additional computational cost in PEEC implementations. The physical meaning is interpreted according to the energy conservation law. Representative radiating units are employed as benchmarks. The proposed method can be applied in the diagnosis and optimization process for signal integrity, EMI, EMC, etc.
