ECCS-0725657Ronald Reano, Ohio State University Research Fdn INTELLECTUAL MERITThis research will capitalize on the discovery of the gigantic transmission band-edge resonance in periodic stacks of anisotropic layers. This finding provides a framework to exploit the unique properties of artificial materials and their application towards creating hybrid radio-frequency (RF) and optical devices that require less power to operate than devices currently in existence. Efforts entail the realization of bulk and planar degenerate band-edge crystal via fabrication in multilayer and multi-tone ceramics, development of non-invasive dielectric electro-optic probes to extract the extraordinary internal electric-field within the crystal, and creation of low power hybrid RF/optical devices by integrating electro-optic material into crystals which exploit the gigantic transmission band-edge resonance. Low power RF/optical devices benefit a broad range of applications spanning modulators in optical communications networks, phase shifters in phased array radars, detection elements in hybrid RF/optical sensors, and mixers in RF-Over-Fiber systems.BROADER SOCIETAL AND EDUCATIONAL IMPACTIt is well-recognized that artificial materials will play a crucial role in developing next generation communication systems and sensors. Technological challenges include the realization of greater bandwidth (optics) and greater mobility (RF) with the concurrent need for increased power efficiency (energy conservation). The gigantic transmission band-edge resonance to be harnessed herewith is an essential key in creating a new class of hybrid RF/optical devices that operate at significantly reduced power to benefit telecommunications, computing, diagnostics, and sensors. Research activities and educational goals will be integrated by developing a new RF/optics curriculum at The Ohio State University. Our goals are to (1) engender hybrid and integrative research thinking, (2) encourage interdisciplinary graduate education, (3) involve undergraduates, underrepresented groups and minorities in research, (4) engage industry and promote economic development.

ECCS-0725657罗纳德Reano，俄亥俄州州立大学研究基金会知识产权这项研究将利用发现的巨大传输带边共振周期性堆叠的各向异性层。 这一发现提供了一个框架，以利用人造材料的独特性质及其应用，创造混合射频（RF）和光学设备，需要更少的功率比目前存在的设备运行。 努力需要通过在多层和多色调陶瓷中制造来实现块状和平面简并带边晶体，开发非侵入性电介质电光探针以提取晶体内的异常内部电场，以及通过将电光材料集成到利用巨大传输带边谐振的晶体中来创建低功率混合RF/光学器件。 低功率RF/光学器件的应用范围非常广泛，包括光通信网络中的调制器、相控阵雷达中的移相器、混合RF/光学传感器中的检测元件以及RF-Over-Fiber系统中的混频器。更广泛的社会和教育影响众所周知，人工材料将在开发下一代通信系统和传感器方面发挥至关重要的作用。 技术挑战包括实现更大的带宽（光学）和更大的移动性（RF），同时需要提高功率效率（节能）。 由此利用的巨大传输带边谐振是创建新型混合RF/光学设备的关键，这些设备可以显著降低功率，从而使电信，计算，诊断和传感器受益。 研究活动和教育目标将通过在俄亥俄州州立大学开发新的RF/光学课程来整合。我们的目标是（1）产生混合和综合的研究思维，（2）鼓励跨学科的研究生教育，（3）让本科生，代表性不足的群体和少数民族参与研究，（4）参与工业和促进经济发展。
