商品描述

The current rapid and complex advancement applications of electromagnetic (EM) and optical systems calls for a much needed update on the computational methods currently in use. Completely revised and reflecting ten years of develoments, this second edition of the bestselling Computational Methods for Electromagnetic and Optical Systems provides the update so desperately needed in this field.

Offering a wealth of new material, this second edition begins with scalar wave propagation and analysis techniques, chiral and metamaterials, and photonic band gap structures. It examines Pontying vector and stored energy, as well as energy, group, and phase velocities; reviews k-space state variable formation with applications to anistropic planar systems; and presents full-field rigorous coupled wave analysis of planar diffraction gratings with applications to H-mode, E-mode, crossed gratings, single and multilayered diffraction grating analysis, and diffraction from anistropic gratings.

Later chapters highlight spectral techniques and RCWA as applied to the analysis of dynamic wave-mixing in PR materials with induced transmission and reflection gratings and demonstrate the RCWA algorithm to analyze cylindrical and spherical systems using circular, bipolar cylindrical, and spherical coordinates. The book concludes with several RCWA computational case studies involving scattering from spatially inhomogeneous eccentric circular cylinders, solved in bipolar coordinates. Many of these examples apply the complex Poynting theorem or the forwardscattering (optical) theorem to validate numerical solutions by verifying power conservation.

Using common computational tools such as Fortran, MATLAB, COMSOL, and RSOFT, the text offers numerous examples to illuminate the material, many of which employ a full-field vector approach to analyze and solve Maxwell’s equations in anisotropic media where a standard wave equation approach is intractable. Designed to introduce novel spectral computational techniques, the book demonstrates the application of these methods to analyze a variety of EM and optical systems.

商品描述(中文翻譯)

目前,電磁(EM)和光學系統的快速和複雜的應用需要對目前使用的計算方法進行急需的更新。經過完全修訂並反映了十年的發展,這本暢銷書的第二版《電磁和光學系統的計算方法》提供了這個領域迫切需要的更新。

這本第二版提供了大量的新材料,首先介紹了純量波傳播和分析技術、手性和超材料以及光子帶隙結構。它檢視了庞丁矢量和儲能,以及能量、群速度和相速度;回顧了應用於異向性平面系統的k空間狀態變量形成;並提出了對H型、E型、交叉光柵、單層和多層光柵分析以及異向性光柵的全場嚴格耦合波分析。

後面的章節突出了光譜技術和RCWA在分析具有誘導透射和反射光柵的PR材料中的動態波混合方面的應用,並展示了使用圓形、雙極圓柱和球座標系統分析圓柱和球形系統的RCWA算法。本書以在雙極座標中解決空間非均勻偏心圓柱體的散射為例進行了幾個RCWA計算案例研究。其中許多例子應用了復雜的庞丁定理或正向散射(光學)定理來通過驗證能量守恆來驗證數值解。

本書使用常見的計算工具,如Fortran、MATLAB、COMSOL和RSOFT,提供了許多例子來闡明材料,其中許多例子採用了全場向量方法來分析和解決在異向性媒介中的麥克斯韋方程,而標準的波動方程方法則難以處理。設計用於介紹新穎的光譜計算技術,本書演示了這些方法應用於分析各種電磁和光學系統。
