- Abstract:
- A surface edge element method is proposed and implemented in the study of electromagnetic scattering fields of general targets.The basis functions for surfaces of arbitrary shape are derived according to the geometrical properties of each triangular patch.The proposed basis functions are 3-D linear functions and the tangential components of the vectors are continuous as the traditional edge element method.Combined field integral equations(CFIE)that include both electrical field and magnetic field integral equations are used to model the electromagnetic scattering of general dielectric targets.Special treatment for singularity is presented to enhance the quality of numerical solutions.The proposed method is used to compute the scattering fields from various targets.Numerical results obtained by the proposed method are validated by results from other numerical methods.
