On the Gain and Link Equation for Reactive Millimetre-wave Surface Wave Propagation System

Surface-wave has been proven to be the third option between wired and wireless communication. It has been proposed to be utilised for inter-machine and on-body communications, because of its on-surface two-dimensional feature. It provides a flexible two-dimensional platform and shows many advantages such as power savings, excellent electromagnetic compatibility characteristic, non-line-of-sight communication over traditional space wave wireless communication systems. When compared to wired systems, surface wave systems can provide a wide band channel for one-to-many/many-to-one communications. This work we will demonstrate our recent work in the concept of surface wave gain and formulate the surface wave wireless link equation for the first time. A 52 GHz 3-dB bandwidth test bed was constructed to validate the theoretical and simulation results in the proposed method and equation.
