  As an attempt to develop a reconfigurable surface architecture that can use
liquid metal such as Galinstan to shape surface channels on demand, this paper
considers a punctured surface where cavities are evenly distributed and can be
filled with liquid metal potentially via digitally controlled pumps. In this
paper, we look at the benefits of such architecture in terms of surface-wave
signal enhancement and isolation, and examine how various system parameters
impact the performance using full wave 3-dimensional electromagnetic
simulations. It is shown that extraordinary signal shaping can be obtained.
