Emergence and applications of novel electronic and electrical technologies have spread into almost every corner of our lives, from patient monitoring to wireless power transmission, and terahertz imaging and sensing. As a result, the range of operating frequencies in electrical and electronic systems has been extended from a low frequency of a few Hertz to terahertz and optical frequency. Such applications have made designs of related electrical and electronic circuits and systems very challenging; this is because circuits and systems are required to be of low cost and small size, and electromagnetic effects and stochastic phenomena, such as spatial field distributions, parasitics, radiation, plasmonics, noises and random material property variations, are no longer negligible. As a result, a single unifying efficient and effective electromagnetic modeling and design platform that can simulate all electrical and electronic phenomena, including noises from low to optical frequency, is very much desirable in order to shorten design cycles and increase competitiveness. Our recent preliminary work in generalizing existing numerical methods has presented the possibility of creating such a unifying platform; it will not only place numerical methods under a single mathematical framework, but also allow easy development of new numerical methods catering to specific problems.
