An Efficient Impedance Calculation Method for Composite Targetswith Periodic Structure

This paper applies an efficient impedance filling technique to calculate the impedance elements of composite model with periodic structure. After analyzing the method of dividing the composite structure by the traditional aggregate basis function, we combine the equivalent dipole moment technique to quickly generate the basis function and reduce the filling time of the impedance matrix equation. This method makes full use of the periodic nature of the model, and simplifies the complex division process. The numerical calculation result shows that this new method can improve the computing speed and reduces the computer memory cost.
