Abstract:
The radiation behaviour of a corner reflector antenna designed using epsilon negative (ENG) artificial wire medium is realized using nonstandard Finite Difference Time Domain (NS-FDTD) method and the results are compared with standard FDTD algorithm. High accuracy NS-FDTD algorithm which requires less iteration for convergence is for the first time implemented for metamaterial corner reflector antenna. This is achieved by extending this powerful algorithm by addressing the stability related issues in conducting media and the proposed work may find potential applications in the simulation studies of dispersive and metamaterial designs.
