Abstract :
The paper presents a new approach to time-domain effective calculation of electromagnetic fields radiated by an UWB sources placed on conducting convex obstacle. The frequency domain uniform theory of diffraction (UTD) and rational approximation exploiting the vector fitting algorithm (VF) is used for deriving the closed form time domain function of the radiated field. The VF algorithm is performed with respect to new generalized variables proportional to frequency but also taking into account geometrical parameters of the obstacle. The Spice simulation is used for calculation of numerical examples.
