Abstract :
We have developed a conformal auxiliary differential equation based dispersive FDTD method using effective permittivities. The calculation of dispersion diagram for plasmonic waveguide formed by an array of silver cylinders is used to validate the proposed algorithm. The comparison with staircase approximations clearly demonstrates the advantage in the accuracy of proposed method for modelling of curved nano-plasmonic structures.
