Summary:
In this study, we propose subgridding techniques in the constrained interpolation profile (CIP) method in order to simulate electromagnetic fields in the presence of objects with fine structures. The subgridding techniques consist of spatial and temporal interpolation at the interface between main coarse grids and local fine grids. In the present study, we consider a two-dimensional problem with TMz polarization. In order to examine the validation of the proposed method, spatial and temporal interpolation schemes are performed separately. Numerical results show that both the interpolation schemes operate successfully, and the relative errors are extremely small in wide frequency band.
