New RF/microwave radio systems are emerging for innovative wireless technology applications such as asset tracking, environmental sensing and medical monitoring. These radios are often required to be low cost, small size and low power consumption and, at the same time, to have multi-channel and multi-standard functionality, to operate at a high frequency and with a possible wide frequency band. These requirements have always presented difficult challenges for radio designers, since high frequency effects such as parasitics, mutual coupling, radiation and interference can no longer be neglected.In addressing the problems, time-domain electromagnetic modelling techniques that can accurately predict radio wave or signal behaviors over a wide frequency bandwidth have been developed and become increasing popular. However, most of these time-domain methods are still constrained by their inherent numerical properties and, therefore, are limited mostly to electrically small structures that are not very useful to real-world problems. The proposed research program is intended to tackle the issue by developing methods and techniques that break with conventional approaches to time-domain modelling.The methodology to be applied will be based on our recently developed theoretical framework that generalizes numerical time-domain methods. With this theory, novel time-domain methods that require no pre-defined numerical grids but instead employ a set of nodes will be developed. Also, new solution and time-domain diakoptic extraction methods will be developed. Since no other similar techniques have been reported so far, the success of this project will present a new break-through in time-domain simulation and optimization methodologies. The end results will be generic time-domain simulators and optimizers as well as novel devices that can be used for a broad range of emerging wireless technology designs and applications.

新的RF/Microwave无线电系统正在为创新的无线技术应用（例如资产跟踪，环境传感和医疗监测）而出现。这些收音机通常被要求低成本，小尺寸和低功耗，同时具有多频道和多标准功能，以高频和可能的频率频段运行。这些要求总是给无线电设计师带来困难的挑战，因为不再忽略了寄生虫，相互耦合，辐射和干扰等高频效应。在解决问题时，时间域电磁建模技术可以准确地预测广泛的频率带频率的无线电波或信号行为，并且已经发展出广泛的流行。但是，这些时间域方法中的大多数仍然受其固有的数值属性的限制，因此主要限于对现实世界中问题不太有用的电气小结构。拟议的研究计划旨在通过开发与时间域模型的常规方法打破的方法和技术来解决该问题。要应用的方法将基于我们最近开发的理论框架，该框架将数字时间域方法推广。有了这一理论，将开发出不需要预定义的数值网格但使用一组节点的新型时域方法。此外，还将开发新的解决方案和时域透明提取方法。由于到目前为止尚未报告其他类似的技术，因此该项目的成功将在时间域模拟和优化方法中提出新的突破。最终结果将是通用的时域模拟器和优化器以及可用于广泛新兴的无线技术设计和应用的新型设备。
