Abstract
This paper presents a robust correction procedure based on the perturbation method to reduce errors around edges and corners related to thin structures via a sub-domain technique. The idea of the method is considered as several scenarios. A sub-domain involving with stranded or massive inductors alone is initially considered. A shielding approximation that neglects end and border effects is then added with an impedance-type condition across a surface. A volume correction is finally introduced to improve the inaccuracies from the shielding approximation. But, this volume correction usually faces with cancellation errors in the calculation of the local fields around corners and curvatures. Thus, in order to treat this inconvenience, a robust correction procedure is developed to take cancellation errors into account. Each sequence of the method is considered separately on its own mesh and domain without depending on other meshes and domains.
