Title :
Real time array launching of localized wave pulsed beam energy
Author_Institution :
Lawrence Livermore Nat. Lab., CA, USA
Abstract :
Summary form only given. The author discussed work done at the Lawrence Livermore National Laboratory in the generation of localized wave (LW) pulse beams. The effective frequency concept has been considered as well as the criteria of the effective Rayleigh distance for a pulsed array. Based on these ideas, the LW pulse has achieved better efficiency than the other control beams and has extended its near-field out to 10 times the expected Rayleigh distance.<>
