Electromagnetic Quasistatic Field Formulations of Darwin Type
摘要：
电磁准静态（EMQS）场，其中辐射效应被忽略，而欧姆损耗和电场和磁场能量被认为是，可以使用达尔文型场模型作为一个近似的完整的麦克斯韦方程。这些EMQS公式通常用磁矢量势和电标量势表示，但不是规范不变的。几个EMQS配方导致不同的规范方程被认为是和分析其结构特性和建模能力和局限性。相关的离散场制剂的背景下的麦克斯韦网格方程的有限积分技术被认为是在频域和时域，并研究其代数性质。数值模拟结果与实验结果的比较。参考解决方案，获得了完整的麦克斯韦方程组的既定配方。
英文摘要：
Electromagnetic quasistatic (EMQS) fields, where radiation effects are neglected, while Ohmic losses and electric and magnetic field energies are considered, can be modeled using Darwin-type field models as an approximation to the full Maxwell equations. Commonly formulated in terms of magnetic vector and electric scalar potentials, these EMQS formulations are not gauge invariant. Several EMQS formulations resulting from different gauge equations are considered and analyzed in terms of their structural properties and their modeling capabilities and limitations. Associated discrete field formulations in the context of the Maxwell-grid equations of the Finite Integration Technique are considered in frequency and time domain and are studied with respect to their algebraic properties. A comparison of numerical simulation results w.r.t. reference solutions obtained with established formulations for the full Maxwell equations are presented.
