While all electrical devices are electromagnetic in nature, there is an important class of devices which can only be understood properly by knowing in detail how the electromagnetic field behaves. These are the "electromagnetic devices" referred to in the title of this proposal and they include many microwave components used in telecommunication systems. For a long time engineers have used computers to simulate the fields in order to predict the performance of their designs, but many of the problems that engineers want to analyze push the limits of even modern computers. Devices are becoming more complex and accuracy requirements greater. For this reason, there continues to be a need for better simulation methods and this proposal focuses on one them, the finite element method (FEM). Specifically, it aims to advance the state of the art in two areas:

虽然所有的电气设备本质上都是电磁的，但有一类重要的设备只有通过详细了解电磁场的行为才能正确理解。这些是本提案标题中提到的“电磁装置”，它们包括电信系统中使用的许多微波元件。长期以来，工程师们一直使用计算机来模拟磁场，以预测其设计的性能，但工程师们想要分析的许多问题甚至突破了现代计算机的极限。设备变得越来越复杂，精度要求也越来越高。出于这个原因，仍然需要更好的模拟方法，本建议侧重于其中一种，即有限元法（FEM）。具体来说，它的目标是在两个领域推进最先进的技术：
