Abstract

The existence of array guided surface waves (AGSWs) on partially finite (finite times infinite) array of dipoles in air have been demonstrated earlier; the work in this paper extends this study to fully finite (finite times finite) planar arrays both in air and on a grounded material slab of infinite extent. Effects of AGSWs on scattering characteristics are examined and a ray interpretation is provided for the edge/corner excitation of AGSWs and conventional substrate surface waves
