Design of a negative refractive index material based on numerical simulation
2016
Abstract Numerical simulation analysis of a new kind of resonator is presented. The proposed structure operates as a magnetic resonator that provides dual band negative permeability behavior as a result of magnetic resonance produced due to self and mutual coupling of the inclusions. It also shows negative permittivity for a broad frequency band. The proposed structure is capable of achieving negative refractive index at the frequency where both negative permittivity and negative permeability overlapping each other. The design of the resonator is simple and, thus, it allows playing with geometric contents for potential applications.
