Analysis of Extinction Properties of Nanostructures Using Method of Moments

The extinction characteristic is one of the most important optical properties of nanostructures, and the extinction cross section is an important parameter to measure the extinction characteristic. Thus, it is of great significance to accurately and efficiently calculate the extinction cross section of the nanostructure. In this paper, the method of moments is first applied to the analysis of extinction characteristics of nanostructures. Then, based on the method of moments, the extinction characteristics of some large-scale nanostructures are solved by the adaptive crossover approximation algorithm.
