Limited diffraction beams from cylindrical arrays

Abstract

The authors propose to launch limited diffraction beams called focus wave mode (FWM) from a cylindrical array. Using this new array geometry, the launching scheme is greatly simplified compare to conventional planar arrays. One single independent generator is used to generate all the driving source signals. It is shown that performance and reconstruction quality of the pulse launched from a cylindrical array are similar to those from circular arrays of same aperture size (same radius).
