Solid state Blumlein line with high dielectric constant polymer-composite

摘要: 以陶瓷聚合物复合介质作为储能介质，砷化镓光导半导体开关作为开关，设计了带状Blumlein线并对其进行了实验研究。实验结果表明，复合介质Blumlein介电常数高达80～250，在21 Ω的匹配负载上获得电压幅值为2 kV，前沿小于5 ns，半高宽约34 ns，波动约±1%的平顶宽为22 ns的电压脉冲，能满足脉冲功率系统小型化的应用要求。

Abstract: The design of strip Blumlein line was presented with the polymer-composite as energy storage dielectric and GaAs-PCSS as circuit switch.The experment results show that relative permittivity of the polymer-composite reaches 80~250, the permittivity and susceptibility of the dielectric do not change under different voltages.The risetime of voltage pulse of the strip Blumlein line is less than 5 ns, the flat top is about 22 ns with ripples of flattop about ±1%. The designed Blumlein line can satisfy the needs of application.
