Abstract :
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.
