Reverse circular Bragg phenomenon

The problem of axial propagation circularly polarized light in a birefringent structurally chiral medium is exactly solved via full electromagnetic analysis. Underlying symmetries the system's characteristic matrix reveal interesting insights, which are confirmed by coupled wave theory. For extreme values chirality, reverse circular Bragg resonance arises negative refraction regime where handedness reversal counterpart modes occurs. A condition identified under birefringence precisely offsets structural rendering simply linearly birefringent. Manufacturing such feasible current metamedia and inorganic materials technology has applications optics, optoelectronics, sensing.
