Abstract :
A promising approach for beam steering of high-voltage transient signals for compact HPEM-systems is presented. The inherent capability of the Rotman-lens to provide true time delays is used to develop a prototype beamformer for an anti-electronics HPEM system in the frequency range from 300 MHz to 5 GHz. Results of simulations and measurements from an upscaled higher frequency prototype are presented.
