Abstract: We report the first realization of a three-dimensional (3D) acoustic double-zero-index medium (DZIM) made of a cubic lattice of metal rods. While the past decade has seen several realizations of 2D DZIM, achieving such a… read more here.

Abstract: The effects of pair ions (O+ & O−) on the existence and propagation characteristics of ion-acoustic double layers (IADLs) are studied in a six-component cometary plasma, consisting of two hot and one colder components of… read more here.
