Surface wave inherently has less propagation loss as it adheres to the surface and minimizes unwanted dissipation in space. Recently, they find applications in network-on-chip (NoC) communications and intelligent surface aided mobile networked communications. This paper puts forward a reconfigurable surface wave platform (RSWP) that utilizes liquid metal to produce highly energy-efficient and adaptive pathways for surface wave transmission. Our simulation results illustrate that the proposed RSWP using Galinstan can obtain a 25\rm dB gain in the electric field for a propagation distance of 35λ at 30\rm GHz where λ denotes the wavelength. Moreover, less than 1\rm dB loss is observed even at a distance of 50λ, and a pathway with right-angled turns can also be created with only a 3.5\rm dB loss at the turn.
