Microwave communication systems have a variety of uses in all aspects of global life. Consider, as an example, a radar receiver. The receiver must be able to detect weak electromagnetic radiation and yet be protected from damage if there is a very large incoming signal. To meet these contradictory requirements, devices known as receiver protectors are installed in front of the receiver. These are designed to allow small signals through but to reflect large signals.Microwave communication systems contain very sensitive components that can be damaged by incident electromagnetic (EM) fields, so installing devices such as receiver protectors is paramount to their needs. Current modelling techniques for these receiver protection devices are incapable of providing sufficiently accurate data at all frequencies of interest to ensure satisfactory protection levels, thus advancements need to be made. The overall aim of the project is to improve the simulation technologies available for the design of GHz systems. One part of the project will measure existing receiver protectors and characterize both their mechanical construction and their RF performance. These measurements will then be compared to simulations of the receiver protectors using existing simulation technologies - any differences between the simulations and experiment will be quantified. The project will then seek to improve the simulation of such devices using cutting edge electromagnetic and device simulation techniques being developed by the Faculty of Engineering, University of Nottingham.

微波通信系统在全球生活的方方面面都有各种用途。以雷达接收器为例。接收器必须能够检测到微弱的电磁辐射，并在有非常大的输入信号时受到保护而不受损害。为了满足这些相互矛盾的要求，被称为接收器保护器的设备被安装在接收器的前面。微波通信系统包含非常敏感的组件，可能会被入射电磁场损坏，因此安装接收器保护器等设备对他们的需求至关重要。目前用于这些接收器保护装置的建模技术不能在所有感兴趣的频率上提供足够准确的数据以确保满意的保护水平，因此需要进行改进。该项目的总体目标是改进可用于GHz系统设计的模拟技术。该项目的一部分将测量现有的接收器保护器，并表征它们的机械结构和射频性能。然后将这些测量结果与使用现有模拟技术对接收器保护器进行的模拟进行比较--模拟和实验之间的任何差异都将被量化。然后，该项目将寻求使用诺丁汉大学工程系正在开发的尖端电磁和设备模拟技术来改进此类设备的模拟。
