Abstract :
We will discuss the reflection and transmission coefficients in the negative index materials. Based on the finite differential time domain approach, we obtain the reflection and transmission coefficients depending on permittivity and permeability at a fixed frequency. The transmissivity and reflectivity will be also examined. Simulation results are in good agreement with the theoretical ones. This technique can be easily extended to the multi-layered structure with negative index materials to design the optical system.
