Artificial intelligence, energy & power systems, internet-of-things (IoT), 5G communications, and materials have emerged as the technology areas that will bring significant changes and impacts on how we work and live in the future. They all encompass novel electronic and electrical circuits and systems for a wide range of applications, from unmanned vehicles to personal health monitoring systems, from wireless power harvesting and transfer to imaging and sensing. The range of operating frequencies has been extended from a low frequency of a few Hertz to terahertz/optical frequency and spatial dimensions of different parts of a component or a system vary from nanometers to tens of meters. These applications have made or will make designs and optimizations of electrical and electronic circuits and systems very challenging: since circuits and systems are required to be of low cost and small size with powerful functionality, not only electromagnetic effects (e.g. field distributions, propagation) but also Multiphysics phenomena (e.g. thermal, force, tongue, plasmonics, quantum) must be considered in design and optimization. They demand for efficient and effective simulation methods to (i) develop new engineered materials, novel components, (ii) shortening design cycles and (iii) increase competitiveness.Our recent work on numerical methods for simulating electromagnetic structures has presented the opportunity and foundation for advancing and expanding the areas of the above-mentioned Multiphysics and multiscale modeling. Based on these methods, we will develop a new generalized method for modeling electromagnetics-coupled thermal, force, photonic, plasmonic, quantum and other physical phenomena, and form a computational platform that unifies most numerical methods for Multiphysics and multiscale modeling including stochastic characterizations. We will expand our modeling theory and develop associated software for Multiphysics and multiscale modeling of electronic and electrical components and systems. We will expand and incorporate our recent work on analytical solutions and eigen-decompositions of time-domain numerical methods and the time reversal least-square technique into the unifying computational method. We will then apply it to model, design and optimize emerging components and systems of wireless power transfer for electronics and automobile charging, mm-wave components and systems for 5G communications, nano- and terahertz/optical imaging devices and systems for detection of biological tissues and chemical agents (e.g. explosives and DNA). The end results of this research program are expected to be not only the computational methods and software packages for Multiphysics and multiscale modeling but also new electrical components, circuits and systems applicable to emerging technology areas.

人工智能，能源和电力系统，物联网（IoT），5G通信和材料已成为技术领域，这些技术领域将对我们未来的工作和生活方式产生重大变化和影响。它们都涵盖了各种应用的新型电子和电路以及系统，从无人车辆到个人健康监测系统，从无线功率收获，转移到成像和传感。操作频率的范围已从几个赫兹的低频扩展到terahertz/组件的不同部分的光学频率和空间尺寸，或者系统从纳米量到数十米不等。这些应用已经制造或将对电路和电子电路和系统进行设计和优化：由于需要电路和系统必须具有低成本和尺寸较小的功能强大，不仅是电磁效应（例如，电场分布，传播），而且还需要多型现象（例如热量，力，舌，舌，plasue，plasemonics和plassmonics），并且是量身定量的。他们要求（i）开发新的工程材料，新颖的组件，（ii）缩短设计周期和（iii）提高竞争力。我们最近的数值方法的工作为模拟电磁结构提供了机会和基础，以促进上述多张物质和多张物质模型的领域。基于这些方法，我们将开发一种新的通用方法，用于建模电磁耦合的热，力，光子，等离子，量子，量子和其他物理现象，并形成一个计算平台，该平台统一了用于多型物理学和多尺度建模的大多数数值方法，包括随机特征。我们将扩展我们的建模理论，并为电子和电气组件和系统的多物理和多尺度建模开发相关软件。我们将扩展并纳入时间域数值方法的分析解决方案和特征分类以及时间逆转最小二乘技术的最新工作。然后，我们将其应用于模型，设计和优化电子和汽车充电，MM波电荷的无线电源传输系统，5G通信，纳米和Terahertz/光学成像设备和系统，用于检测生物组织和化学剂（例如爆炸物和DNA）。预计该研究计划的最终结果不仅是多物理和多尺度建模的计算方法和软件包，而且还将是适用于新兴技术领域的新电气组件，电路和系统。
