However, this method, didn\u2019t receive a lot of scientific attention, since the introduced complexity wasn\u2019t quite justified by the obtained gain in maximum time step size. Nevertheless, there is still a strong motivation to study this formulation, since it can potentially be, in combination with high order accuracy FDTD approaches, a significant tool to combat the accuracy deterioration due to numerical dispersion. A method of choice for termination of CE-FDTD computational domain was the convolutional perfectly matched layer (CPML), since it is considered to be superior over other commonly used techniques. Yet, the application of CPML in CE-FDTD environment isn\u2019t straightforward. In this paper a modification of conventional CPML is performed in order to be used for termination of CE-FDTD computational domain. The modified CPML, along with CE-FDTD algorithm has been implemented in an own developed simulation environment and tested through various simulation cases. The functionality of the proposed CPML is illustrated on the example of a dipole antenna. The observed behavior of the boundary region fully corresponds to the propagation through the free space, without any undesirable reflections.<\/td>\n<td width=\"66\"><a href=\"http:\/\/elth.ucv.ro\/fisiere\/anale\/2014\/1.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter  wp-image-191\" src=\"http:\/\/elth.ucv.ro\/fisiere\/anale\/wp-content\/uploads\/2015\/03\/images1.jpg\" alt=\"images\" width=\"100\" height=\"104\" \/><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Abstract\u00a0 A complex-envelope finite difference time domain (CE-FDTD) algorithm has been proposed in the literature as one of FDTD formulations that is very general.
