  1. Feed network is an important part of short - wave multimode multi - feed antenna system. the design of feed network is a pivotal technique in the process of projecting antenna system. above all, this paper expounds the basic notion and procedure of analyzing and designing feed network applying the substructure analyzing theoretics of interconnect - net. basing on these jobs, some radical methods of analyzing and measuring the substructure of feed network are presented. using these methods, substructure is analyzed and measured. finally, a measured database of substructure of feed network is established

  2. The first generation uses the shortwave ( 0. 8 m - 0. 9 m ) and multimode fiber, and the second generation uses long wave ( 1. 3 m, 1. 5 m ) and singlemode fiber. and now the third generation uses dwdm fiber - communicating technic. sichuan wide band transmission net optical fiber system is an important project of sichuan telecom

    寬帶傳輸網從採用短波長（ 0 . 8 - 0 . 9 m ）和多模光纖的第一代光纖通信技術到採用長波長（ 1 . 3 m 、 1 . 55 m ）和單模光纖的第二代光纖通信技術發展到了今天採用dwdm （ densewavelengthdivisionmultiplexing ）的第三代光纖通信技術。
  3. Multimode interference ( mmi ) couplers based on the self - imaging effect are rapidly getting popular because of the advantage of low loss, compact size and large fabrication tolerance. the thesis studied the principle of the mmi coupler. the optical field distribution in the multimode wave - guide is modeled by eim and mode propagation analysis method ( mpa )
