Numerical Study of an A-Shape Negative Refractive Index Material
並列摘要
Metamaterial designing is an important issue in order to reduce the complexity and for the extensive use in various potential applications. This paper presents an A-shape novel metamaterial structure which simultaneously exhibits negative permittivity and negative permeability. An electromagnetic wave simulation is performed, and the results show that the proposed metamaterial unit cell is capable of achieving a negative refractive index. Furthermore, a left hand prism was designed composed of metamaterial unit cells. Simulation of the left hand prism proves the presence of a negative refractive index. The proposed design is easy to fabricate compared to the complex structures, due to the simple geometry, and could be used in various applications.
