Efficient high-order analysis of bowtie nanoantennas using the locally corrected Nystrom method

摘要

It is demonstrated that the Locally Corrected Nystrom (LCN) method is aversatile and numerically efficient computational method for the modeling ofscattering from plasmonic bowtie nanoantennas. The LCN method is a high-orderanalysis method that can provide exponential convergence. It is straightforwardto implement, accurate and computationally efficient. To the best of theauthors knowledge, the high-order LCN is here applied for the first time to 3Dnanostructures. Numerical results show the accuracy and efficiency of the LCNapplied to the electromagnetic analysis of nanostructures.
