摘要
In this paper, a novel periodic 2D all-dielectric metamaterial based on dielectric trimer is proposed. The electromagnetic responses are explained by the corrected equations of motion using coupled mode theory (CMT). An abnormal vanishment mode phenomenon is also discovered and explained using the zero sum effect of magnetic dipole, by which the relative bandwidth of the metamaterial has been improved significantly compared with other structures. The presented design is easy for fabrication and can be applied in microwave region by scaling the dimensions of the cubes.
