The chiral Swiss roll metamaterial is a resonant, magnetic medium that exhibits a negative refractive band for one-wave polarization. Its unique structure facilitates huge chiral effects: a plane polarized wave propagating through this system can change its polarization by 90° in less than a wavelength. Such chirality is at least 100 times greater than previous structures have achieved. In this paper, we discuss this extreme chiral behaviour with both numerical and analytical results.
手性瑞士卷超材料是一种共振磁性介质，对于单波极化表现出负折射带。其独特结构有助于产生巨大的手性效应：通过该系统传播的平面偏振波可以在小于一个波长的距离内将其偏振改变90°。这种手性比以前的结构所实现的至少大100倍。在本文中，我们用数值和分析结果来讨论这种极端的手性行为。
