在电磁设备的设计中，几何形状的准确表示对设备的性能起着至关重要的作用。特别是对于加速器腔，为了保证电磁场与加速粒子的同步，控制本征模的频率是很重要的。这项工作的主要兴趣在于利用蒙特卡罗模拟和随机配置来评估本征模对几何变化的敏感性。选择等距分析方法进行空间离散，可以精确地处理几何域及其变形，同时保证精确和高度规则的解。
In the design of electromagnetic devices the accurate representation of the geometry plays a crucial role in determining the device performance. For accelerator cavities, in particular, controlling the frequencies of the eigenmodes is important in order to guarantee the synchronization between the electromagnetic field and the accelerated particles. The main interest of this work is in the evaluation of eigenmode sensitivities with respect to geometrical changes using Monte Carlo simulations and stochastic collocation. The choice of an Isogeometric Analysis approach for the spatial discretization allows for an exact handling of the geometrical domains and their deformations, guaranteeing, at the same time, accurate and highly regular solutions.
