摘　　要：针对多路高功率微波合成技术中,合成器采用扩大尺寸的方式容易产生高次模式的问题,在数值模拟的基础上,设计了一种用于高功率微波合成的双色板,可对X波段下两路相同极化方向的高功率微波进行高效合成。当电磁波入射角度为45°时,该双色板对9.3 GHz±50 MHz高功率微波的反射效率大于99%,对9.7 GHz±50 MHz高功率微波的透射效率大于99%,且抑制了高次模式的产生,实现了8 GW的功率容量及紧凑化设计的要求。In this paper,a dichroic plate structure is designed for high power microwave(HPM)synthesis,which can efficiently synthesize high power microwaves with the same polarization direction in dual pass-band for X-band.A simulation is conducted on the dichroic plate unit and array.The simulation results show that when the incident angle of the electromagnetic wave is 36~52°,the reflection efficiency of the dichroic plate for HPMs with a frequency of 9.3 GHz±50 MHz is greater than 99%,and a transmission efficiency of the dichroic plate for HPMs with a frequency of 9.7 GHz±50 MHz is greater than 98%.This dichroic plate suppresses the generation of high-order modes and can withstand microwave irradiation with a power of 8 GW with a compact structure.
