摘要: 在数值模拟的基础上,设计了一种用于高功率微波合成的X波段同频带双色板。微波斜45入射时,该双色板在9 GHz到9.3 GHz内反射效率大于99%,在9.7 GHz到10 GHz内传输效率大于99%,可以用于实现两路高功率微波的同极化合成。利用电磁场全波分析软件,建立了双色板数值模型,分析了该双色板的场增强因子和功率容量问题。Abstract: In this paper, on the basis of numerical simulation, an X-band dichroic plate for high power microwave combination is designed. With an incidence angle of 45, the reflection efficiency for the dichroic plate is more than 99% from 9 GHz to 9.3 GHz; The transmission efficiency is more than 99% from 9.7 GHz to 10 GHz. The dichroic plate can be used in combination of HPMs with identical polarization. Making use of full wave analysis software, a numerical model of the dichroic plate is established. The field enhancement factor and power handling capacity is also analyzed.
