Abstract :
The STTD (spacetime triangle diagram) technique is applied for investigation of scalar and electromagnetic wave booms emanated by physically feasible pulsed line sources whose front travels faster than the wavefront. It is shown that a rough approximation of linearly growing source is sufficient for obtaining finite-amplitude wave-boom description everywhere outside the line of source-pulse trajectory.
