Local Electromagnetic Field Characterization for Portable Wireless Communications

提案#:ECS-9626599 PI名称/机构：Jennifer T. Bernhard/新罕布什尔大学这位在新罕布什尔大学任教的女PI申请了研究计划拨款，以启动一个项目来模拟和测量便携式无线通信单元的局部电磁环境，强调用户和单元的机箱是电磁子系统的一部分。提出的研究有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高容量的数据和视频传输问题。建议的研究将探索最重要的缺失子领域之一，反向链接（用户和接收单元电气子系统）。反向链接几乎总是比正向链接弱，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。与此同时，反向链路是FCC监管最严格的地方，因为这是直接影响用户的电磁环境。这项研究计划拨款计划是明确和精心设计的初步研究，为完整的研究计划提供重要的支持。它包括时域有限差分仿真和电磁模拟“人体”吸收器和接收机系统的辐射方向图测量。天线放置的问题将在一种新的底盘内设计的背景下进行探讨，这种设计可以利用新的辩证材料。在此RPG授权期间，特别强调的是与工业界建立联系，并获得用于测试的真实设备。在杜克大学高度相关的博士后研究期间，PI在电磁模拟“人体”吸收器方面建立了专业知识。PI与无线通信行业合作伙伴的积极联系可以预期为拟议的努力增加很多。我强烈建议按照提议的金额$18,000.00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.
