Abstract
An efficient numerical modal method for modeling a lamellar grating in conical mounting is presented. Within each region of the grating, the electromagnetic field is expanded onto Legendre polynomials, which allows us to enforce in an exact manner the boundary conditions that determine the eigensolutions. Our code is successfully validated by comparison with results obtained with the analytical modal method.
摘要
提出了一种用于模拟锥形安装中层状光栅的高效数值模态方法。在光栅的每个区域内，将电磁场展开为勒让德多项式，这使我们能够以精确的方式施加确定本征解的边界条件。通过与解析模态方法得到的结果进行比较，成功验证了我们的代码。
