| 1 | 基于平面肖特基二极管的W波段检波器显示文摘肖特基二极管技术为常温下毫米波信号的检测提供了有效的解决方案。它具有极低的寄生电容和级联电阻,可用于该频段的倍频器、混频器和检波器当中。相比于Galey Cell和热辐射测定器(Bolometer),基于肖特基二极管的直接检波技术具有低噪声、高反应率和常温使用的特点。本文介绍了一种基于波导结构的零偏置肖特基二极管检波器,采用E面探针传输波导基模电磁波,通过阻抗匹配实现微带线到二极管的耦合。测试结果表明,在-30 d Bm输入功率下:电压反应率的峰值可达8 900 V/W;在75 GHz^105 GHz的频率范围内,电压反应率在1 000 V/W以上。 | 刘海瑞 POWELL Jeff VIEGAS Colin ALDERMAN Byron 俞俊生 | 2016 | 太赫兹科学与电子信息学报2016，14，5： | 3 |

| 3 | Analysis of a Plasmonic Based Optical Fiber Optrode With Phase Interrogation显示文摘光纤维 optrodes 是吸引人的由于他们在遥远的地点执行点测量的能力察觉到设备。主要,他们对生物化学的察觉到面向,相当经常支持了由荧光灯、分光镜技术,但是与当目的具有高测量性能时,也考虑的 refractometric 途径,特别地当焦点在提高可测量分辨率上时。在这个工作,我们跟这个对象讲话,建议并且分析纤维的特征眼的 optrode 依靠 plasmonic 相互作用。一个线性地逐渐变细的光纤维尖端被一个双覆盖盖住:内部的 -- 银薄电影并且在它上 -- 绝缘的层与允许完成的这联合,在一个特定的波长范围,出现对包围媒介的折射索引敏感的 plasmonic 回声(SPR ) 相互作用。典型地,察觉到结构的 SPR 的讯问被执行,就分光镜的技术而言,但是原则上,远更好的表演能在位于以内的特定的波长就光的阶段的读物而言被获得光谱 plasmonic 回声。这是在建议光纤维 optrode 配置的上下文这里被学习的途径。执行的分析显示出有有调节厚度的绝缘的钛氧化物层的内部层启用敏感阶段读并且允许纤维的操作的银的联合在第三扇电信波长窗户中的眼的 optrode 传感器。 | H.

| 4 | Development of Junction Elements from Study of the Bionics显示文摘The applications of bionic methodology developed by the Laboratory of Design and Material Selection as basis in the creation of junction elements were demonstrated. These elements favor the application of Ecodesign in reference to the effec-tiveness of product dismount aiming the reduction of ambient impact in all its phases of use. The creation,the development and the confection of new junction elements were described,and case studies of new products developed specifically with this purpose were presented. | Wilson Kindlein Junior Luis Henrique Alves Cndido André Canal Marques Sandra Souza dos Santos Maurício da Silva Viegas | 2007 | Journal of Bionic Engineering2007，4，1： | 2 |
