Miniaturized electromagnetic band gap structures for wireless applications

本研究旨在利用新型材料开发小型化电磁带隙（EBG）结构，用于高速封装和结构中的电磁干扰滤波和噪声抑制。它还旨在为EBG提供一个有效的介质模型，使利用EBG的系统和电路易于建模。小型化目标将采用先进的高介电常数材料、优化的拓扑结构和LTCC技术中的垂直集成。该项目预计将对需要小型化封装的小型无线系统在100MHz至20GHz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。这项工作预计不仅在印刷电路板和封装技术方面，而且在小型和低轮廓天线和相控阵天线设计方面都有很大的影响。随着天线尺寸与波长比的不断减小和天线带宽的不断扩大，超宽带小型化EBGs成为必不可少的使能技术。太赫兹电磁波技术最近重新成为对爆炸物和毒品等隐蔽有害物质进行非侵入性检测的有力竞争者。太赫兹技术的主要缺点是太赫兹振荡器和放大器的成本。我们提出使用EBG材料的低成本来源（用于产生反向行波）。我们计划将EBG设计和概念扩展到高GHz和低太赫兹频率范围。在这种情况下，纳米技术与先进材料的结合对于实现具有可调电容和电感特性的谐振器至关重要。

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.
