Long-range coupling of waveguides
Recently the authors proposed a model and related analysis on waves in long-range metamaterials. Nonlocal elasticity can be produced by several interacting forces acting between particles at long distance, as Coulomb or magnetic-static forces. The chance of introducing this long-distance forces has a disruptive effect in the elastic dynamics. In fact, classical elasticity is based only upon closest particles interaction in which short range-elastic forces act.
