摘要：

The terahertz (THz) radiation absorption of graphene layers in a pseudomagnetic field, prepared on top of a onedimensional photonic crystal (1DPC), is investigated theoretically. Discrete Landau levels can be found in graphene in a pseudomagnetic field. Strong THz transitions may be found between the discrete Landau levels. The THz absorption of graphene can also be tuned by varying either pseudomagnetic field or the distance between the graphene and the 1DPC. © 2014 Chinese Physical Society.
