Abstract :
A high-order accurate Legendre pseudospectral time-domain (PSTD) method has been established for accurate analyses and simulations of electromagnetic problems, in particular, plasmonics related problems. Here it is employed to simulate transmission characteristics of two-dimensional plasmonic ring resonators based on the metal/insulator/metal (MIM) waveguide structure. The formulated PSTD method is based on a penalty scheme and a multidomain approach. The same penalty scheme is used to derive a pseudospectral frequency-domain (PSFD) method which offers an alternative technique to analyze the same resonators.
