Abstract

Water has been introduced as a unique component of all-dielectric multifunctional metasurfaces for microwaves. Typically absorbing properties of arrays in free-air arrangement have been analyzed. Here we report on promising performance of a water-filled metasurface in a microwave waveguide setup. The metasurface has a one row of cylindrical cavities. Being filled with water the metasurface exhibits effective modulation properties opening and closing the waveguide transmission channel upon 90° rotations. It acts as a wire grid polarizer, however temperature dependence of water dielectric characteristic, possible deformation of the cavities shapes and rotation of elements form a set of effective stimulus for possible tuning of transmission/reflection properties.
