Local Electromagnetic Field Characterization for Portable Wireless Communications

提案#：ECS-9626599 PI名称/机构：詹妮弗·T·伯恩哈德/新汉普郡大学参考女性PI在新汉普郡大学任教的第一年，已申请研究规划拨款，以启动一项计划，模拟和测量便携式无线通信单元的本地电磁环境，强调用户和单元的底盘作为电磁子系统的一部分。拟议研究的几个方面是新颖和重要的。无线通信这一热门领域的重要性正在迅速增长。这一领域的研究目前参差不齐。预计在不久的将来会出现更大的数据量和视频传输问题。拟议的研究将探索最重要的缺失的子领域之一，反向链路(用户和接收单元的电气子系统)。反向链路几乎总是比前向链路更弱，因此它是性能的限制因素。然而，除了基站(前向链路)之外，对电磁配置的研究很少。同时，反向链路可能是FCC监管最严格的地方，因为这是直接影响用户的电磁环境。这项研究规划补助金建议清楚而审慎地设计为初步研究，为完整的建议提供重要的支持。它包括有限差分的时间域模拟和辐射方向图测量与电磁模拟的“人”的吸收以及接收系统。天线放置的问题将在一种新的机箱内设计的背景下进行探索，该设计可以利用新的辩证材料。在这项RPG赠款期间，将特别强调发展与工业的联系，并获得用于测试的真实设备。在杜克大学进行高度反响的博士后研究期间，PI已经建立了使用电磁模拟“人体”吸波材料的专业知识。PI与无线通信行业合作伙伴的积极联系可以为拟议的工作做出很大贡献。我强烈建议以18,000.00美元的拟议数额提供资金。

Proposal #: ECS-9626599 PI Name/Institution: Jennifer T. Bernhard/ University of New Hampshire The referenced female PI in her first year as faculty at University of New Hampshire has requested Research Planning Grant Funds to initiate a program to simulate and measure the local electromagnetic environments of portable wireless communication units, emphasizing the user and the unit's chassis as part of the electromagnetic subsystem. Several aspects of the proposed research h are novel and important. The topical area of wireless communications is rapidly growing in importance. Research within this field is currently spotty. Higher volume data and video transmission problems are expected in the near future. The proposed research will explore one of the most important missing sub-fields, the reverse link (the user & the receiving unit electrical sub-system). The reverse link is almost always the weaker than the forward link, hence it is the limiting factor in performance. However very little research has been done on electromagnetics configurations other that the base station (the forward link). At the same time, the reverse link is where the heaviest FCC regulation may be expected to fall since this is the electromagnetic environment which directly affects the user. This Research Planning Grant proposal is clearly and carefully designed as preliminary study to provide important support for a full proposal. It includes both finite difference time domain simulation and radiation pattern measurement with electromagnetically simulated "human" absorbers as well as the receiver systems. Questions of antenna placement will be explored tin the context of a new in-chassis design which could take advantage of new dialectic materials. Special emphasis will be placed on developing connections with industry and obtaining real equipment for test during this RPG grant. The PI has established expertise in working with electromagnetically simulated "human" absorbers during highly re levant post-doctoral research at Duke University. The PI's energetic liaisons with wireless communications industry partners can be exepcted to add very much to the proposed effort. I strongly recommend funding at the proposed amount of $18,000.00.
