Surface impedance model for nano-scale device communications over an interface

To take into account the impact of an underlying half-space on the communication channel between nano-scale nodes, the surface-impedance-based model is proposed. To verify this approach, its results are compared to that of the singularity-based model developed for the particular half-space. Finally, by using the impedance-based approach, it is shown that the gain of the channel between nano-scale devices can be notably increased due to the contribution of surface waves.
