Abstract :
This paper discusses the recent developments on the finite-difference time-domain (FDTD) method in highly dispersive regimes. Focus is given on two examples of interest: EM energy propagation via plasmon resonances in metal nanoparticles (MNPs) chains, and frozen modes in nonreciprocal MPCs. In the former case, J-E-H FDTD formulations with Drude dispersion model are employed to analyze nanoscale chains comprising of gold nanospheres. In the latter case, D-H and B-E FDTD formulations associated with general constitutive relations are extended to verify the striking properties of nonreciprocal MPCs
