Time-domain analysis of negative refractive index materials by FDTD method

Negative refractive index materials are artificial materials with permittivity and permeability both negative within certain microwave frequency band. FDTD method is used to simulate the distribution of electromagnetic field inside and around the negative refractive index materials by the treated Maxwell’s equations for TE mode. Unstable situation during calculation is avoided. Numerical experiment results of the distribution of electromagnetic fields in the area are given.
