根据Joyner等人的想法[Europhys. Lett. 107，50004（2014）]，实现了具有服从T^{2}=-1的反对酉对称性T的微波图。预期这样的系统的Kramers双峰被清楚地确定，并可以解除一个扰动，打破了反酉对称性。所观察到的Kramers双峰的谱级间距分布与高斯辛系综对具有这种对称性的混沌系统的预测一致。
Following an idea by Joyner et al. [Europhys. Lett. 107, 50004 (2014)], a microwave graph with an antiunitary symmetry T obeying T^{2}=-1 is realized. The Kramers doublets expected for such systems are clearly identified and can be lifted by a perturbation which breaks the antiunitary symmetry. The observed spectral level spacings distribution of the Kramers doublets is in agreement with the predictions from the Gaussian symplectic ensemble expected for chaotic systems with such a symmetry.
