论文摘要
分析发现了均质磁化四面体的流量和消极张量场。四面体是四个三角形面的特殊情况，具有恒定的磁化齐射表面密度，为此我们还确定了张量场。张量场在开源微磁性和磁模拟框架中实现，并与从FEM溶液中获得的磁场进行了比较，显示出极好的一致性。该结果对于一般的磁静态学和微磁尤其是重要的，因为使用常规网格划分技术离散的任意体的反电磁磁场可以通过这种方法显着简化。
The stray- and demagnetization tensor field for a homogeneously magnetized tetrahedron is found analytically. The tetrahedron is a special case of four triangular faces with constant magnetization-charge surface density, for which we also determine the tensor field. The tensor field is implemented in the open source micromagnetic and magnetostatic simulation framework MagTense and compared with the obtained magnetic field from an FEM solution, showing excellent agreement. This result is important for modeling magnetostatics in general and for micromagnetism in particular as the demagnetizing field of an arbitrary body discretized using conventional meshing techniques is significantly simplified with this approach.
