Efficient Method for Obtaining Derivatives of Current Vector for AWE Techniques

In this paper, the improved asymptotic waveform evaluation (AWE) are outlined as the efficient, based on method-of-moments, technique for obtaining broad-band response of the radiators/scatterers. The proposed approach allows to make conventional AWE techniques more effective with respect to time of analysis and memory requirements. The technique consists in fast algorithm for evaluation of impedance matrix derivatives and current vector derivatives, i.e. the most important elements for AWE technique.
