Firstly, we research the Vlasov antenna with reflector mainly. A new method to calculate the radiation of the antenna is founded with Vectorial Theory of Diffraction, and the corresponding program is made. The reflective characters of Vlasov antenna are studied with Moment Methods, and the results show that the total reflected energy is less than 0.25%. The radiation patterns of the antenna are analyzed, and the formulas to estimate the wave beam parameters and to design the antenna are provided. The feasibility of radiating high-order modes by Vlasov antenna is also discussed and verified. The hermetization of the Vlasov antenna is researched and the results show that with such kinds of hermetization the antenna can work under gigawatt level. The design of the mode converter from TEM to TMoi is studied, which is useful when the TEM coaxial mode is radiated by Vlasov antenna. At last, the flared-end Vlasov antenna is also discussed.

在Vlasov天线方面：用矢量绕射理论建立了天线辐射场的计算模型并编写了计算程序，该程序计算结果在主瓣上与实验测量吻合良好，近旁瓣也基本一致；利用矩量法计算了天线的反射系数，表明该天线有较小的反射，总的能量反射小于0.25％；详细分析了天线的辐射特性，给出了天线辐射波束相关参数的估算公式和天线设计公式；进一步研究和论证了Vlasov天线辐射高阶轴对称模的可行性；对天线的密封方式和功率容量进行了讨论，结果表明在不需很大密封罩的情况下可以获得GW级的功率容量；为了用Vlasov天线辐射同轴TEM模，研究了TEM-TM_(01)模式转换器的设计，得到了一些基本规律；最后，介绍和分析了带有锥形喇叭的Vlasov天线。

According to the property of EBB, scanning electron beam was considered as plane heat source instead of spot heat source in this paper. Aiming at the problems to measure the real-time temperature and residual stress of radiator difficultly at high temperature, the two-dimensional finite element models were established. Based on the thermal elastic-plasticity, the temperature fields and stress fields of EBB 6139T and 6204T radiator by two kinds of process were simulated by the software of ANSYS. It is of great value and significance to guide actual production.
