在这里，我们报道了一种由堆叠的准自互补特殊透射面组成的棱镜，它允许垂直和水平极化分别在V波段内同时左手和右手传输，对于两种偏振都允许在W波段内右手传输。由S参数反演出的无限结构的数值色散图和垂直入射下的有效折射率，结合有限积分的时间域模拟，预测了单负和双正双折射。然后在毫米波(V波段和W波段)通过楔形实验实验证明了这种不寻常的单负双折射和规则双正双折射。楔形实验使我们可以用简单的几何方法来检查每个分量的折射。用斯奈尔定律反演了有效折射率，并与色散图和用商业软件CST Microwave StudioTM计算的S参数的反演法进行了比较。
Here we report a prism made of stacked quasi-self-complementary extraordinary transmission surfaces which allows simultaneously left- and right-handed propagation within the V-band for vertical and horizontal polarizations, respectively and right-handed propagation within the W-band for both polarizations. The numerical dispersion diagram of the infinite structure and effective indexes of refraction retrieved from S-parameters under normal incidence together with the finite integration time domain simulations predict single negative and double positive birefringence. The unusual type of birefringence single negative and regular double positive birefringence are afterwards demonstrated experimentally at the millimeter-waves (V- and W-bands) by the wedge experiment which lets us check, using a straightforward geometrical method, the refraction of each component. The effective index of refraction is retrieved via the Snell's law and compared to those obtained through the dispersion diagram and the retrieval method from S-parameters computed with the commercial software CST Microwave StudioTM.
