  题目:Waveguide Flange Design and Characterization of Misalignment at Submillimeter Wavelengths

  时间:2013.4.11. 星期四 10:00-11:00 AM

  地点:电四楼310会议室

  报告人:李慧霖 博士

  主要内容:

  Recent technological developments are enabling components and instruments for realizing submillimeter (from 300 GHz to 3 THz) applications in a wide variety of fields, such as radio astronomy, communications, high resolution radars, imaging systems, and biomedical science. As interest in submillimeter applications have emerged, measurements of complex scattering parameters using vector network analyzers (VNAs) have become progressively extended into the terahertz frequency range. However, the measurement precision and accuracy of these instruments is limited by interconnection quality, repeatability, and the lack of traceable standards. In response to this need, the P-1785 working group of the IEEE has been undertaking a study since 2008, aimed at providing recommendations for a new international standard waveguide interface for use above 110 GHz. This talk discusses the improved interfaces currently being considered by IEEE P-1785 group, specially the ring-centered waveguide flange, and several new characterization methods for qualifying connection repeatability and absolute mismatch of these interfaces at submillimeter wavelengths.

  报告人简介:
