A hexagonal lattice of quantum waveguides is considered with thickening or thinning
of ligaments, which form open waveguides in the periodic nano-structure. Propagation of
localized waves along the open connected and disconnected waveguides is studied and nodes
in the lattice are indicated that support trapped modes with the exponential decay in all
directions.
Keywords: carbon nano-structure; propagation of localized waves. |
