| Abstract: | The spectral analysis technique of digital signal processing is firstly introduced to develop a new general absorbing boundary condition for the Finite Difference Time-Domain Method. Test results show that the new absorbing boundary condition can greatly reduce the wave reflection in boundarys, and it is simpler and more efficient than the previous boundary conditions. |
