研究了具有不同旋转对称度的复杂缝隙阵列的太赫兹波传输特性。我们的实验结果表明，具有六重旋转对称性的椭圆形孔径是实现偏振无关，高效，频率选择性传输太赫兹辐射的最合适的形状。系统地了解THz传输特性对于实现具有特定电磁响应的通用平台和定制设计的金属设备是有用的。(C)2012年，美国光电仪器工程师学会（SPIE）。[DOI：10.1117/1.OE.51.11.119002]
We investigate the terahertz (THz) transmission characteristics of complex slot arrays with various order of rotation symmetry. Our experimental results reveal that an asterisk-shaped aperture with sixfold rotational symmetry is the most appropriate shape for realizing polarization-independent, highly efficient, and frequency-selective transmission of THz radiation. A systematic understanding of the THz transmission characteristics is useful for achieving versatile platforms and custom-designed metallic devices with specific electromagnetic responses.
