Abstract :
A combined method based on the finite-difference method (FDM) and the charge-simulation method (CSM) is proposed for electric field calculation. In this method, the entire field is divided into two domains, which are analyzed separately with FDM and CSM. These domains are coupled together using the continuity condition of potential and normal dielectric flux density at the boundary. The proposed method has the advantages of both the FDM and the CSM and could be applied to curved electrodes and multidielectrics in open space. Example applications are provided to support the combined method
