... We will assume the simplest case of an exponentially decreasing interaction between single dielectric layers i.e. Jm−n = Jo e−λ|m−n| [12]. Since the problem cannot be efficiently treated by anlytical means, we followed a numerical approach. Figs. 5, 6, 7 and 8 are shapes of the light intensity on a ...
