| 摘 要： | 研究了一种用于GW级高功率微波耦合输出的新型线极化高功率微波双工器，该双工器由周期性的金属圆柱组成。对该双工器的Floquet空间谐波影响因素进行了讨论，得到了双工器空间谐波选择的重要规律，并以此设计了一个S/X波段线极化高功率微波双工器。对其进行的低功率冷测实验发现，该双工器对S/X波段的反射效率和透射效率分别高于97%。在进一步的高功率实验研究中，利用S和X波段1.8 GW，80 ns的高功率微波照射没有发现微波击穿。

| Abstract: | A novel diplexer for the coupling output of GW level microwaves has been investigated, which consists of an array of periodically spaced cylindrical rods. The factors influencing the selection of spatial harmonics for the diplexer were researched, and some important rules for the design of the diplexer were obtained. A cylindricalrod diplexer for the coupling output of S/X band GW level microwaves was designed accordingly. The low power experiments revealed that, its S-band reflection and X-band transmission efficiencies were both higher than 97%. In further high power experiments, the diplexer was operated with microwaves of 1.8 GW and 80 ns, and no microwave breakdown was observed. |
