摘要

Our previous work shows that the use of two time-varying anisotropic layers on the basis of transformation optics can calculate the electric field in microwave applicators of regular shapes with moving elements in translation accurately and efficiently. However, it is difficult to deal with applicators of irregular shapes, which is widely used in practical applications. In this article, we extend this work to the calculation of electric field in applicators of irregular shapes. In the proposed two-dimensional model, the motion region is truncated by rectangular anisotropic coated layers, including four edge layers and four corner layers. In this case, the motion region is independent of applicator shapes. Therefore, the electric field can be calculated equivalently with arbitrary irregular applicator shapes. The results show good accuracy and efficiency, which indicates that the improved method has a good potential for modeling the heating process of practical microwave applicators with elements in translation.
