A Least Square Method for Solving Parabolic Wave Equations with Impedance Boundary Conditions

In this paper a least square method is used to solve the parabolic wave equation which can model impedance boundary conditions of the propagation environment. In this method proper basis functions are used to expand electromagnetic field in successive computation steps. The proposed method is faster than its finite-difference counterpart and needs much less memory size against it.
