论文摘要
通过完整的电磁分析，可以精确地解决光学活性结构性手性介质中圆极化光的轴向传播。该系统特征矩阵的某些对称性揭示了新见解，这通过耦合波理论证实。对于现在可以通过超材料访问手性的极端价值，在负面折射状态下发生了反向圆形的bragg共振，在这种情况下发生交手逆转。确定了一种条件，在该条件下，光活动抵消了结构性手性，从而使培养基简单地折断。
The axial propagation of circularly polarized light in an optically active structurally chiral medium is exactly solved via full electromagnetic analysis. Some symmetries of the system's characteristic matrix reveal new insights, which are confirmed by coupled wave theory. For extreme values of chirality, now accessible via metamaterials, a reverse circular Bragg resonance arises in the negative refraction regime where handedness reversal of counterpart modes occurs. A condition is identified under which optical activity offsets structural chirality, rendering the medium simply birefringent.
