| Abstract: | A modified version of the finite-difference time-domain method with increased memory efficiency is applied to the computation of the radiation from a cylindrical monopole. And the graphical displays presented for the transient near-zone and far-zone radiation from the antenna provide physical insight into the radiation process. The novel approach compared with the normal finite-difference time-domain has higher efficiency. |
