To electromagnetic society, it is one of the biggest interests to develop full-wave based engineering friendly electromagnetic modeling approaches for coupling and radiation problems that are applicable in multi-physics and electromagnetic compatibility researches. In this talk, the partial element equivalent circuit (PEEC) method, a unique bridging method between electromagnetics and circuit theory, is employed and innovated to address new challenges in electromagnetic analysis. It brings us interesting new approach and insight to practical applications.
Firstly, a novel derived equivalent circuit model of arbitrary shape graphene sheets is developed. It is also a new contribution to PEEC for handling dispersive and anisotropic medium. Secondly, a physics-based model size reduction (PMSR) method is developed for key coupling analysis in the power integrity (PI) for the power distribution network (PDN) design and optimization in integrated circuit (IC), packaging, and printed circuit board (PCB). Lastly, we devoted great efforts in redefining the fundamental electromagnetic radiation mechanism through a distributive modeling approach. Both finite difference type model partitions and characteristic mode based global basis analysis approached are employed, cross-referenced, and used for understanding the basic radiation mechanism. The approach can be instructively applied to EMC/EMI and other power distribution computations.
All proposed algorithms have been verified and demonstrated by various examples. Compared to conventional approaches, they provide more modeling conveniences, calculation efficiencies and deeper physics insights of the working mechanism.
