色散性傳輸線及其應用

演講人:徐敬文教授,IEEE fellow

時間地點2月28(周二)上午10:00,物理與信息工程學院祥聯廳

講座內容Dispersion is a physical phenomenon which states that?signals of?different frequencies to suffer different time delays. As a result,?a wave package of signal having different frequencies will be distorted after it propagates through a finite length of a medium. Thus, dispersive?effect is generally treated as an undesirable noise in most microwave communications.

In this presentation, we elaborate on the dispersive microstrip?transmission?lines whose dispersion behavior is controllable. Some basic microstrip dispersive lines featured with controllable dispersion and all-pass characteristic will be presented. The plausible applications to microwave analog signal processing including TDMA and FDMA will be addressed. These schemes are generally feasible in the baseband signal processing arenas and we bring it up to RF frequency. The other possible application to microwave radar pulse amplification will also be discussed.
