Abstract

In this paper, we develop an efficient and accurate procedure of electromagnetic multipole decomposition by using the Lebedev and Gaussian quadrature methods to perform the numerical integration. Firstly, we briefly review the principles of multipole decomposition, highlighting two numerical projection methods including surface and volume integration. Secondly, we discuss the Lebedev and Gaussian quadrature methods, provide a detailed recipe to select the quadrature points and the corresponding weighting factor, and illustrate the integration accuracy and numerical efficiency (that is, with very few sampling points) using a unit sphere surface and regular tetrahedron. In the demonstrations of an isotropic dielectric nanosphere, a symmetric scatterer, and an anisotropic nanosphere, we perform multipole decomposition and validate our numerical projection procedure. The obtained results from our procedure are all consistent with those from Mie theory, symmetry constraints, and finite element simulations.

对散射物体的电磁多极进行高效、精确的数值投影。
在本文中,我们利用列别杰夫正交法和高斯正交法进行数值积分,开发了一种高效、精确的电磁多极分解程序。首先,我们简要回顾了多极分解的原理,重点介绍了两种数值投影方法,包括曲面积分和体积积分。其次,我们讨论了列别杰夫正交法和高斯正交法,提供了选择正交点和相应加权因子的详细配方,并使用单位球面和正四面体说明了积分精度和数值效率(即使用极少的采样点)。在演示各向同性介质纳米球、对称散射体和各向异性纳米球时,我们进行了多极分解,并验证了我们的数值投影程序。我们的程序得到的结果与米氏理论、对称约束和有限元模拟得到的结果一致。

期刊介绍: Frontiers of Optoelectronics seeks to provide a multidisciplinary forum for a broad mix of peer-reviewed academic papers in order to promote rapid communication and exchange between researchers in China and abroad. It introduces and reflects significant achievements being made in the field of photonics or optoelectronics. The topics include, but are not limited to, semiconductor optoelectronics, nano-photonics, information photonics, energy photonics, ultrafast photonics, biomedical photonics, nonlinear photonics, fiber optics, laser and terahertz technology and intelligent photonics. The journal publishes reviews, research articles, letters, comments, special issues and so on. Frontiers of Optoelectronics especially encourages papers from new emerging and multidisciplinary areas, papers reflecting the international trends of research and development, and on special topics reporting progress made in the field of optoelectronics. All published papers will reflect the original thoughts of researchers and practitioners on basic theories, design and new technology in optoelectronics. Frontiers of Optoelectronics is strictly peer-reviewed and only accepts original submissions in English. It is a fully OA journal and the APCs are covered by Higher Education Press and Huazhong University of Science and Technology. ● Presents the latest developments in optoelectronics and optics ● Emphasizes the latest developments of new optoelectronic materials, devices, systems and applications ● Covers industrial photonics, information photonics, biomedical photonics, energy photonics, laser and terahertz technology, and more
