标题： Decoupled field integral equations for electromagnetic scattering from homogeneous penetrable obstacles

摘要： 我们提出了一种分析均匀可穿透体电磁散射的新方法。 我们的方法基于将控制麦克斯韦方程组重新表述为两个解耦的矢量亥姆霍兹系统：一个用于电场，另一个用于磁场。 这使得能够推导出无共振的第二类弗雷德霍姆方程，这些方程在所有频率下都是稳定的，对散射体的亏格不敏感，并且对于所有被动材料（包括具有负介电常数或磁导率的材料）都是可逆的。 我们将这些称为解耦场积分方程。 显示英文摘要

摘要： We present a new method for the analysis of electromagnetic scattering from homogeneous penetrable bodies. Our approach is based on a reformulation of the governing Maxwell equations in terms of two uncoupled vector Helmholtz systems: one for the electric feld and one for the magnetic field. This permits the derivation of resonance-free Fredholm equations of the second kind that are stable at all frequencies, insensitive to the genus of the scatterers, and invertible for all passive materials including those with negative permittivities or permeabilities. We refer to these as decoupled field integral equations.
