【摘要】 近年来,双极化频率选择雷达吸波体(Frequency selective rasorber,FSR)得到了研究人员的广泛研究。本文提出了一种极化选择传输/反射FSR。通过适当地控制施加在PIN二极管上的电压,所提出的FSR可以从传输模式切换到反射模式。通过对其等效电路模型的分析表明了其工作原理。最后的仿真结果表明,当PIN二极管处于关断状态时,可以在5.24 GHz～5.76 GHz的范围内实现传输。其在5.42 GHz处的插入损耗低至-0.174 dB。当PIN二极管导通时,反射峰值在5.36 GHz处具有-0.38 dB的损耗。此外,在工作频带的两侧具有两个吸波带。由于它们的偏置电路被衬底隔离,极化调制可以由沿x和y方向加载的PIN二极管单独控制。该设计在电磁屏蔽和雷达散射截面缩减方面有着潜在的应用。更多还原

【Abstract】 In recent years,dual-polarization frequency selective rasorber(FSR) has been extensively studied.In this paper,a polarization-selective transmission/reflection FSR is proposed.The proposed FSR can switch from the transmission to reflection modes by properly controll the bias voltage applied on the PIN diodes.The analysis of the equivalent circuit model demonstrates its operating principle.The full-wave simulation results show that when the PIN diodes are in the OFF state,transmission is achieved in the range of 5.24 GHz～5.76 GHz.The insertion loss at 5.42 GHz is as low as-0.174 dB.When the PIN diodes are turned ON,the reflection peak has a loss of-0.38 dB at 5.36 GHz.Moreover,there are two absorption bands on both sides of the operating frequency band.Since their bias circuits are isolated by the substrate,the polarization modulation can be individually controlled by PIN diodes loaded along the x-and y-directions.The design has potential applications in electromagnetic shielding and radar cross section reduction.更多还原
