Multi physics multi scale modeling of microwave circuits and systems hybridizing circuit, electromagnetic and thermal modeling

Abstract

Modeling of complex systems requires that a systematic approach be adopted for multi scale and multi physics modeling. The current state of physical modeling tools in the arena of microwave and electromagnetic model is considerably mature enabling discrete problems to he considered. The real need is for hybridization of discrete modeling systems to obtain a seamless simulation environment from atoms to systems. The paper explores a strategy for multi physics multi scale modeling of microwave circuits and systems. It presents a framework guiding research in the development of electromagnetic and microwave modeling tools

Advanced RF and Microwave Design Optimization: A Journey and a Vision of Future Trends

“…Highly accurate multi-physics microwave design optimization is another very challenging application area, even at the device-, component-, or circuit-level. RF and microwave design automation considering multi-scale modeling combined with multi-physics simulation remains a "grand scientific and engineering challenge" [85]. Ultimately, the multi-physics approach to design optimization aims at intelligently coupling the most relevant physical domains, typically including transport phenomena, full-wave electromagnetics (EM), electrical, thermal and mechanical domains.…”
