Reflection engineering plays an important role in optics. For conventional approaches, the reflection tuning is quite challenging in a loss-free component. Therefore, a simple approach to tune the reflection is highly desired in plenty of applications. In this paper, we propose a new design of metasurface with just one single layer dielectric structure to tune the reflection of an interface by destructive interference in a subwavelength scale. By arranging the orientation of nano-antennas, the reflectivity tuning from 20% to 90% can be achieved at the wavelength of 1550 nm. Moreover, such reflectivity tuning of the designed metasurface works at the tunable wavelength from 1500 nm to 1600 nm. This ultra-thin solution can achieve similar performance as the traditional bulky components without diffraction orders, while the design and fabrication are much simple and flexible. The ultra-thin and tunable properties indicate the great potentials of this method to be applied in laser fabrication, op-tical communication and optical integration.
