We designed an omnidirectional reflector for both the transverse electric (TE) and the transverse magnetic (TM) modes in one dimensional liquid-crystal-based heterostructure composed of the ThueMorse multilayered structure and periodic medium. The electrical tunabilities of the reflector are theoretically studied by the Berreman’s matrix method.
The omnidirectional reflective bands (ORB) of the TE and TM modes have different behaviours. For the TE mode, the ORB is electric independent, and is wider than its counterpart of the TM mode. The ORB of the TM mode becomes narrow with the increase of the incident angle. The polarity-independent ORB was observed in the proposed structure.
