| 摘 要： | 采用几何光学模型详细研究了边廊模回旋管中Vlasov模式变换器的工作原理,利用等效像源模型结合矢量绕射理论分析了通过此模式变换器的辐射场.考虑W波段边廊模回旋管的具体参数,通过数值计算,讨论了通过Vlasov模式变换器后辐射波束的场分布特性.结果表明,Vlasov模式变换器将回旋管中的高阶边廊模式转换为自由空间的高斯模式,且远场的高斯场型较近场更好.

| Abstract: | The principle of Vlasov mode converter for whispering-gallery mode gyrotron was studied in detail by using a geometric optics model.The radiation field passing through the mode converter was analyzed by using the equivalent image source model and the vector diffraction theory.After considering some particular parameters of W-band whispering-gallery mode gyrotron,the field distribution of radiated beam passing throngh Vlasov mode converter was discussed by numerical calculation.The results indicate that the ... |
