Integrated Macro-models of Networks and Fields for the Simulation of Complex Systems

该提案涉及复杂高速电子系统设计中的一个关键领域，即如何在存在极端的几何、电路和材料复杂性的情况下对其电磁行为进行有效的研究。由于在这种情况下很常见，技术是将系统划分为多个子系统，然后使用最适合其特点的技术对每个子系统进行建模。然后，需要组合不同的子模型，以充分考虑所有交互。这种分割、子系统建模和聚合的过程在所有物理领域都是非常具有挑战性的，但在高频应用中尤其如此(电磁波不尊重边界--它们沿大距离传播和耦合)。在本提案中，我们的目标是使用一系列基于场、基于网络和行为的数值模型来解决这些问题。我们将我们自己在构建复杂的多尺度系统宏观模型方面的专业知识与我们的合作伙伴的专业知识结合起来，以解决一个对信息和通信技术的先进发展至关重要的具有挑战性的问题，这一问题渗透到所有工程应用中。这项研究计划的成功完成将使工业界能够使用复杂的混合建模能力来分析和设计复杂的电磁系统，例如将多种复杂功能结合在一个手持单元中的现代移动电话。

The proposal addresses a critical area in the design of complex high-speed electronic systems, namely, how to perform efficient studies of their electromagnetic behaviour in the presence of extreme geometrical, circuit and material complexity. As it is common in such cases the art is to segment the systems to subsystems and then model each one using a technique best suited to its peculiarities. Then, the various sub-models need to be combined to account fully for all interactions. This process of segmentation, sub-system modelling and aggregation is very challenging in all physical domains but it is particularly so in high-frequency applications (electromagnetic waves do not respect boundaries-they propagate and couple along large distances).In this proposal we aim to address these issues using a range of numerical models, field-based, network-based and behavioural. We combine our own expertise in constructing sophisticated macro-models of multi-scale systems with that of our partners to address a challenging problem of crucial importance to the advanced development of information and communications technologies which pervade all engineering applications. Successful completion of this research programme will make available to Industry a sophisticated hybrid modelling capability to analyse and design complex electromagnetic systems such as typified by a modern mobile phone which combines in a single handheld unit a multitude of complex functions.
