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，即如何在极端几何、电路和材料复杂性的情况下对其电磁行为进行有效研究。因为在这种情况下很常见，所以技术是将系统分割成子系统，然后使用最适合其特性的技术对每个子系统进行建模。然后，需要将各种子模型组合起来，以充分考虑所有交互。分割，子系统建模和聚合的过程是非常具有挑战性的，在所有的物理域，但它是特别是在高频应用（电磁波不尊重边界，他们传播和耦合沿着大的距离）。在这个建议中，我们的目标是解决这些问题，使用一系列的数值模型，基于场，基于网络和行为。联合收割机将我们自己在构建多尺度系统的复杂宏观模型方面的专业知识与我们的合作伙伴相结合，以解决对信息和通信技术的先进发展至关重要的挑战性问题，这些技术渗透到所有工程应用中。这项研究计划的成功完成将为工业界提供一个先进的混合建模能力，以分析和设计复杂的电磁系统，如典型的现代移动的电话，它结合在一个单一的手持单元的多种复杂的功能。

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.
