We demonstrate that periodic arrays of single-wall metallic carbon nanotubes
(CNTs) exhibit electromagnetic wave properties which are strongly different that possessed
by single CNTs. The distinctive feature of CNT arrays is a hyperbolic dispersion of
electromagnetic waves, propagating in these structures. Electromagnetic interaction between
carbon nanotubes leads to dramatic slowdown of eigenwaves in CNT arrays.
Keywords: carbon nanotube array; slow waves; hyperbolic dispersion; hyperbolic media
