摘要
设计了一种基于开口谐振环的偏振转换器,该结构是由两开口圆环和上下两层光栅的超材料组成。这种偏振转换机制的分析是基于法布里波罗共振腔原理和相应共振点处电场分布。文中利用CST微波工作室探究了偏振转换器的电磁特性,结果表明该结构能在太赫兹范围内实现了宽带的(0.28~1.82THz)高效的偏振转换(偏振转换率(PCR)远高于0.9)和90°的偏振旋转。根据其电磁特性,该结构可以被用于90°偏振旋转器、偏振转换器。
In this paper, a Linearly Polarized Converter Based on Split Ring Resonator metamaterial has been proposed, which consist of Double-Split Ring Resonator inserted between two layers of twisted sub-wavelength grating. The mechanism of polarization conversion based on Fabry-Perot-like cavity. Numerical result demonstrate that 90°polarization rotators and broadband high efficient polarization conversion ratio(PCR higher than 0.9) can be achieved by CST MWS within Terahertz frequency range. According the electromagnetic properties, the structure can be applied as 90° polarization rotator and single-transmission device
