In the last years, metasurfaces have attracted much attention due to the capability of tailoring the response in a sub-wavelength scale and their compact implementations. In the particular case of reflective metasurfaces, also called metamirrors, anomalous reflection is a fundamental transformation between two plane waves propagating in different directions. The analysis of this scenario is important for evaluating the potential use of engineered surfaces for more complex functionalities, such as lenses or holograms. Despite the apparent simplicity of this problem, current designs suffer from low efficiency or high complexity. In this paper, we present the analysis and design of an acoustic anomalous reflector device based on power-flow conformal metamirrors. The proposal is experimentally verified showing good agreement with the theoretical predictions.
