When dealing with cozmplicated dot-based lattice structures, the traditional approach used by micromagnetic simulators is to treat the entire lattice structure as a single body containing magnetized and non-magnetized regions. This approach is not computationally favorable due to excessive processing and storage requirements. The concept of a mutual demagnetizing tensor can be used for minimizing this load. In this paper, we show the feasibility of our approach for patterned dots in rhomboid lattice geometries.
