MAS-MBPE application for analysis of channel plasmon polaritons

摘要

A Method of Auxiliary Sources (MAS) combined with Model-Based Parameter Estimation (MBPE) technique is applied to numerical simulations of plasmonic nano-structures. The MAS is a numerical technique for the calculation of electromagnetic fields in the frequency domain. The adaptive MBPE algorithm is based on Cauchy's formula and operates in the frequency domain to extrapolate or interpolate from a narrowband set of data to a broadband set of data. The data can be either computed or measured over a specified frequency range. For computed data the sampled values of the function and a few low order derivatives are calculated from a Maxwell solver and are then used to reconstruct the function. MBPE belongs to the class of auxiliary techniques and can be added to any field solver. In this paper a Channel Plasmon-Polariton (CPP) is analyzed to demonstrate the efficiency of MAS-MBPE.
