Waves path in an elastic membrane with selective nonlocality

Nonlocal long -range effects are at the base of new phenomena investigated by the authors. In one dimensional systems, this permits the chance of modifying the phase and group velocity of the waveguide, even producing waves transporting energy backwards. In the two-dimensional case a richer scenario is opened. This paper investigates the chance of transporting the energy over a two-dimensional domain through vibrations that can follow a given path. The relationship between the path and the connection template is investigated. This directional effect is shown presenting the theoretical analysis and corroborating its results through numerical simulations
