基于等离子体超材料的超宽带吸波体设计
|
摘要
为了在横电(TE)波下获得可调谐的超宽带吸收频谱以及在横磁(TM)波下获得较高的反射率,利用等离子体超材料和集总电阻设计了一种电磁吸波体,并采用全波仿真法对其吸收率、反射率、表面电场图、表面电流图和能量损耗图进行了计算,讨论了其结构参数及电阻对吸收率和反射率的影响。研究结果表明,通过激励不同的等离子体谐振区域,不但能改善吸收特性,还能获得可调谐的吸收频谱;设计的电磁吸波体不仅能实现对TE波的超宽带吸收,还能实现TE波和TM波的极化分离。
In order to obtain a tunable ultra-broadband absorption spectrum under transverse electric(TE)waves and a high reflectivity under transverse magnetic(TM)waves,an electromagnetic absorber is designed based on the plasma metamaterials and the lumped resistors.Its absorptivity,reflectivity,surface electric field diagram,surface current diagram and energy loss diagram are calculated by the full wave simulation method.The influences of its structural parameters and resistance on the absorptivity and reflectivity are investigated.The research results show that,by means of the excitation for different plasma resonance ranges,not only the absorption property is improved,but also the tunable absorption spectrum can be obtained.As for the designed electromagnetic absorber,not only the ultra-broadband absorption of TE waves can be realized,but also the polarization splitting of TE and TM waves can be achieved.
