In this work we performed a detailed numerical analysis on the static and dynamic properties of magnetic antidot arrays as a function of their geometry. In particular, we explored how by varying the shape of these antidot arrays from circular holes to stadium-shaped holes, we can effectively control the magnetic properties of the array. Using micromagnetic simulations we evidenced that coercivity is very sensitive to the shape of antidots, while the remanence is more robust to these changes. Furthermore, we studied the dynamic susceptibility of these systems, finding that it is possible to control both the position and the number of resonance peaks simply by changing the geometry of the holes. Thus, this work provides useful insights on the behavior of antidot arrays for different geometries, opening routes for the design and improvement of two-dimensional technologies.

在这项工作中，我们对磁性解毒剂阵列作为其几何函数的静态和动态特性进行了详细的数值分析。特别是，我们探索了如何通过将这些反点阵列的形状从圆形孔更改为体育场形状的孔来有效控制阵列的磁性能。通过微磁模拟，我们证明了矫顽力对解毒剂的形状非常敏感，而剩磁对这些变化更健壮。此外，我们研究了这些系统的动态磁化率，发现仅通过改变孔的几何形状就可以控制共振峰的位置和数量。因此，这项工作为不同几何形状的解毒剂阵列的行为提供了有用的见解，
