摘要
这篇论文将是去年在2006年IEEE航空航天会议上发表的一篇题为“多层介质的电磁研究”的论文的延续,作者是Joel P. Booth。本文将讨论多层材料的基本电磁分析过程。这个讨论将包括计算机模拟,现实世界的情况和研究生研究。将探讨不同材料之间的关系及其对电磁能的影响。这项工作是在位于阿拉巴马州亨茨维尔红石兵工厂的航空和导弹研究、开发和工程中心(AMRDEC)应用传感器、制导和电子理事会的射频技术部进行的。本文将探索利用材料特性和几何结构来重定向电磁能,作为一种创造低成本、低损耗的天线罩材料(或天线罩设计)的手段,以扩大平衡和电子控制相控阵的电流范围。目前,由于(1)万向节的机械限制和(2)由于系统的移相器元件在大角度产生大副瓣的限制,大多数导弹导引头在方位角和仰角上被限制为60度。其概念是在不增加机械手段或更密集的加工的情况下扩大转向范围,同时不妨碍多模式配置的功能。从这项工作中获得的数据将用于选择新的导弹导引头系统参数。这项研究的影响可能会推动成本、制造和新的设计概念。结果也可能影响雷达设计模式的组合以实现任务。本研究的目标是开发和研究一种低成本、低损耗、易于制造和设计新颖的概念。
Electromagnetic Redirection thru Material Manipulation
This paper will be a continuation of the work presented last year at the 2006 IEEE Aerospace Conference in a paper titled," Electromagnetic Study of Multilayer Media", Joel P. Booth. This paper will discuss the process of a basic electromagnetic analysis for a multilayer material. This discussion will include computer simulations, real world situations and graduate studies. The relationships between different materials and their effects on electromagnetic energy will be explored. This effort is being conducted in the RF Technology Division of the Applied Sensors, Guidance, and Electronics Directorate of the Aviation and Missile Research, Development, and Engineering Center (AMRDEC) on the Redstone Arsenal in Huntsville, Alabama. This paper will explore using material properties and geometric configurations to redirect electromagnetic energy as a means create a low-cost, low-loss radome material (or radome design) to extend the current range of both gimbaled and electronically-steered phased arrays. At the present time, most missile seekers are restricted to 60deg in azimuth and elevation due to (1) mechanical limitations of the gimbal and also to (2) limitations of electronically steerable systems due to the phase shifter elements of the system creating large sidelobes at large angles. The concept is to extend steering range without the addition of mechanical means or more intensive processing while not impeding the function of multimode configurations. The data obtained from this effort will be used in the selection of new missile seeker system parameters. The effects of the research could drive cost, manufacturing, and new design concepts. The results could also effect the combination of modes in radar design to achieve the mission. The goal of this research is to develop and investigate a concept that is low-cost, low-loss, easy to manufacture, and novel in design.
