Miniaturized electromagnetic band gap structures for wireless applications

这项研究旨在利用新材料开发小型化的电磁带隙(EBG)结构，用于高速封装和结构中的电磁干扰过滤和噪声抑制。它还旨在为EBG提供一个有效的介质模型，使利用EBG的系统和电路的建模变得容易。在LTCC技术中，将采用先进的高介电常数材料、优化的拓扑结构和垂直集成来追求小型化目标。该项目预计将对需要小型化封装的小型无线系统在100 MHz至20 GHz频率范围内的电磁噪声抑制产生重要影响。这项工作将包括材料开发和表征。预计这项工作不仅将对印刷电路板和封装技术产生强大的影响，而且将对小型和低轮廓天线以及相控阵天线的设计产生重大影响。随着天线尺寸波长比的不断减小和天线带宽的不断扩大，超宽带小型化EBG成为一种必不可少的使能技术。太赫兹电磁波技术最近重新崛起，成为非侵入性检测爆炸材料和毒品等隐蔽和有害物质的有力竞争者。太赫兹技术的主要缺点是太赫兹振荡器和放大器的成本。我们提出了使用EBG材料的低成本源(用于产生反向行波)。我们计划将EBG的设计和概念扩展到高GHz和低THz频率区域。在这样的体制下，纳米技术与先进材料相结合，将是实现具有可调电容和电感特性的谐振器的关键。

This proposes research is intended to develop miniaturized Electromagnetic Band Gap (EBG) structures using novel material for the purpose of electromagnetic interference filtering and noise suppression in high-speed packages and structures. It is also intended to provide an effective medium model for the EBG that will allow easy modeling of systems and circuits that utilize EBG. The miniaturization objective will be pursued using advanced high-permittivity material, optimized topology and vertical integration in LTCC technology. The project is expected to have an important impact on electromagnetic noise suppression in the 100MHz to 20GHz frequency range for small-in-size wireless systems requiring miniaturized packages. This work will include material development and characterization. This work is expected to have a strong impact not only in printed circuit board and packaging technology but also in small and low-profile antennas and phased-array antenna design. As the size to wave length ratio of antennas continue to decrease and as antennas continue to have wider bandwidths, ultra wideband miniaturized EBGs becomes an essential enabling technology. THz electromagnetic waves technology has recently reemerged as a strong contender for non-invasive detection of concealed and harmful substances such as explosive material and drugs. The primary drawback of THz technology is the cost of THz oscillators and amplifiers. We propose low-cost sources involving EBG material (for the generation of backward traveling waves.) We plan to extend EBG design and concepts to the upper GHz and lower THz frequency regimes. In such regimes, nano technology in conjunction with advanced materials will be critical in achieving resonators with tunable capacitive and inductive properties.
