Local Electromagnetic Field Characterization for Portable Wireless Communications

提案编号： ECS-9626599 主要研究者姓名/机构： 詹妮弗·T伯恩哈德/新罕布什尔州大学 所提及的女PI在她担任新罕布什尔州大学教员的第一年就请求研究规划补助基金启动一项计划，以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作为电磁子系统的一部分。建议的研究h的几个方面是新颖的和重要的。 无线通信的热门领域的重要性正在迅速增长。目前，这一领域的研究参差不齐。 预计在不久的将来会出现更大容量的数据和视频传输问题。拟议的研究将探索最重要的缺失子领域之一，反向链路（用户接收单元电气子系统）。 反向链路几乎总是比前向链路弱，因此它是性能的限制因素。 然而，很少有研究已经做了其他的基站（前向链路）的电磁配置。 同时，反向链路是最重的FCC法规可能会下降，因为这是直接影响用户的电磁环境。 这个研究规划补助金提案是明确和精心设计的初步研究，为完整的提案提供重要的支持。 它包括时域有限差分模拟和电磁模拟“人”吸收体以及接收机系统的辐射方向图测量。 天线放置的问题将探讨在一个新的底盘设计，可以利用新的辩证材料的背景下。 特别强调将放在发展与工业界的联系，并获得真实的设备进行测试，在此RPG赠款。PI在杜克大学进行高度相关的博士后研究期间，已经建立了使用电磁模拟“人类”吸收体的专业知识。 PI与无线通信行业合作伙伴的积极联系可以预期将大大增加拟议的努力。 我强烈建议按提议的18，000.00美元供资。

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.
