微波加热是体积加热,加热均匀,时间短,效率高。加热薄片状材料的微波系统,需要一个带有缝隙的设备,作为传送带的出入口,由于这个缝隙的存在,会有微波能从缝隙泄漏出来。为了把这些泄漏能限制到允许的程度,可使用滤波器把这些能量反射回去,本文论述的群岛状滤波器就是为此而设计的。群岛状滤波器是在波状滤波器的基础上发展起来的,它是在波状滤波器的波状节上开一些纵向槽,能够抑制高次模。群岛状滤波器中各金属小岛处于纵向槽和横向槽之间。低和高阻抗线段由增加和降 Microwave heating is the volume of heating, heating evenly, time is short, high efficiency. A microwave system that heats a sheet-like material requires a device with a gap as the entrance to the conveyor belt through which microwaves can leak out of the gap due to the presence of this gap. To limit these leaks to permissible levels, filters can be used to reflect these energies back and forth, and the quasar-shaped filters discussed in this article are designed for this purpose. The archipelago filter was developed on the basis of the wavy filter, which is to open some longitudinal slots in the wavy section of the wavy filter, which can suppress the high-order mode. The islands in the archipelago filter are between the longitudinal and lateral slots. Low and high impedance segments increase and decrease
