Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Due to the strong capability to control electromagnetic (EM) wave, metasurfaces have garnered considerable interest and brought in many intriguing EM functional devices. However, most of such devices can only work in either transmitted or reflected mode, and it is still very challenging to achieve a simultaneous control of reflection and transmission in one device. Here, we present a cascaded metasurface which integrates the resonant and geometrical phase cells, to manipulate the transmitted and reflected wave independently. By specific design of phase distribution, the reflected and transmitted wavefront can be respectively reshaped on the shared aperture at two different frequency bands. As a proof of concept, a bidirectional beam deflector is realized by our metasurface and experimentally demonstrated at the microwave region. Both simulated and experimental results show that the transmitted and reflected beams can be simultaneously deflected to the predesigned angles. Furthermore, this metasurface exhibits isotropic EM responses under the different linear polarized wave in the reflected mode, while behaves anisotropic EM responses under the different circular polarized waves in the transmitted mode. Our approach provides a simple way to realize full-space EM manipulation, which could be developed for potential applications in mutlifunctional devices and integrated systems.
