Abstract :
The scalar wave formulation of computation region and the first-order absorbing boundary condition are given by Maxwell´s equations. Then the residuals of entire computation region are presented. The weak form solutions of wave equation are described by take integration over computation domain and its boundary. According to the principle of equivalence, the implementation of extrapolation from 2D time harmonic field to far field is described. Finally, a numerical example is given to illustrate the feasibility of the presented scheme.
