Analysis and optimization of active tunable microwave absorber

  • 摘要: 为解决无源雷达吸波材料带宽有限的问题,基于传输线理论设计了一种有源可调微波吸收体.该吸收体是在Salisbury屏的拓扑结构基础上,用基于PIN二极管可控的有源频率选择表面(FSS)代替传统的电阻层.反射率测量结果表明,通过改变二极管的偏置电流可以动态调节吸收体的最佳吸波频率;当偏置电流在0~0.5mA之间变化时,吸收体的最佳吸波频率在7~12.5GHz频率范围内动态调整.基于遗传算法,优化设计了一种具有双极化吸波特性的十字型可调微波吸收体,仿真结果表明该吸收体在5.6~17.6GHz范围内实现了最佳吸波频率的可控迁移.
