Abstract. A time domain Method of Moments algorithm (TD-MoM) is combined with the time domain version of the Uniform Theory of Diffraction (TD-UTD). By use of the TD-MoM the fields radiated from thin wire structures positioned in free space are determined. The TD-UTD is applied to calculate the fields scattered by a perfectly conducting screen. Both techniques are hybridized by adding possible reflected and diffracted fields in the TD-MoM algorithm and by using the TD-MoM solution to calculate the fields which impinge on to the screen. To show the accuracy of the developed hybrid method, numerical results are compared to results obtained by established frequency domain numerical codes.
