复合式多模喇叭是第四章所论述的变参数多模波纹喇叭的特例,它由四段不同参数的波导段连接而成如图10.1所示。它的第一段是很短的波纹段,其后三段是不同锥角的光壁波导。
Composite multi-mode speaker is a special case of the variable-parameter multi-mode ripple horn discussed in Chapter 4, which consists of four sections of waveguide sections of different parameters connected as shown in Figure 10.1. Its first section is a very short corrugated section, the latter three sections are optical wall waveguides with different cone angles.
