IEEE 杰出演讲人 Yahya Rahmat-Samii 教授

题目:The Art and Science of Antenna Near-Field Measurements and Diagnostics: From fundamentals to     recent Developments (天线近场测量和诊断的艺术与科学:从基础到新近的发展)
地点:东南大学(四牌楼校区)李文正楼   6楼  北614会议室
主办:IEEE APMTT-EMC Joint Nanjing Chapter
 东南大学  毫米波国家重点实验室
 江苏省电子学会  天线与微波专业委员会
内容提要: This presentation will provide the participants with a novel way to understand the fundamental concepts behind modern antenna near field measurement and diagnostic techniques. Starting from basic electromagnetic principles, the underlying concepts governing simulations, designs and operations of planar near field measurements and diagnostics techniques will be reviewed. Modern measurement schemes such as plane-polar and bi-polar scanning will be highlighted. Advances in applying these techniques to millimeter-wave measurements will be reviewed. Representative measurement results of reflector and array antennas will be presented. The importance of near field diagnostic techniques will be discussed through some unique test cases.  Finally, the topic of phaseless measurement techniques and algorithms will be presented demonstrating the potential applications of these techniques in modern antenna measurements. The following topics will be presented: (a) Fundamental of EM concepts for antenna characterizations including antenna radiated fields, ideal dipole, solution of wave equations and special functions, (b) fundamentals of various near-field measurement techniques including equivalence theorem, spectral formulation and probe corrections, (c) Understanding antenna near-field diagnostic techniques including simulation models, back-projections, sampling theorems, (d) Case studies of several reflector and array antenna measurements and diagnostics, and (e) Phaseless measurements and recent advances including why phaseless measurements, phase retrieval algorithms and measured results.
