The method proposed is based on the fast Fourier transform (FFT). The different steps illustrating the principle of the method is described. It is composed of three successive steps: the synchronization of the input excitation spectrum <em>I</em>(<em>f</em>) and the given frequency data <em>H</em><sub>0</sub>(f), the convolution of the two inputs data and then, the determination of the time-domain emissions <em>H</em>(t). The feasibility of the method is verified with standard EM 3D simulations. In addition to this method, an extraction technique of the time-dependent z-transversal EM NF component <em>X<sub>z</sub></em>(<em>t</em>) from the frequency-dependent <em>x</em>- and <em>y</em>- longitudinal components <em>H<sub>x</sub></em>(<em>f</em>) and <em>H<sub>y</sub></em>(<em>f</em>) is also presented. This technique is based on the conjugation of the plane wave spectrum (PWS) transform and FFT. The feasibility of the method is verified with a set of dipole radiations. The method introduced in this paper is particularly useful for the investigation of time-domain emissions for EMC applications by considering transient EM interferences (EMIs).</p>}, number={2}, journal={Advanced Electromagnetics}, author={Liu, Y. and Ravelo, B. and Ben Hadj Slama, J.}, year={2012}, month={Sep.}, pages={26–40} }
