| Abstract: | This paper uses the finite-difference time-domain （FDTD） method to analyze the total field calculating of a perfectly conductive cylinder with perfect matched layer （PML） absorbing boundary conditions and obtain the numerical solution. It is proved that the method is applicable and efficacious in total field calculating. The influence caused by different sources and PML components upon the result is presented. |
