I. Introduction
With the advancement of modern equipment, such as antennas and microwave circuits, several complex structures are designed and expanded into its application. It is known that electromagnetic propagation can be absorbed effectively with the anisotropic coatings for the military aircraft surface, which avoid the enemy radar monitoring [1]. In other engineering application, such as geological exploration, deep-sea discovery, and integrated optics, we will face more anisotropic materials as their background. However, the current algorithms are all stuck in the technical processing of geometric meshing in three-dimensional (3-D) space [2], and many high-performance methods are considered to solve these anisotropic problems [3]. Therefore, how to improve the current algorithms and save the computer memory is meaningful research.
