Metasurface Retroreflector for Controlling Parasitic Surface Waves on Bodies of 5G Mobile Phones
F. S. Cuesta, V. A. Lenets, A. Díaz-Rubio +2
The smartphone, as a media device, should offer a large-size screen and fast data rates in a well-packed device. Emergent 5G technologies based on millimeter waves need efficiently…
Multiphysics metamirrors for simultaneous manipulations of acoustic and electromagnetic waves
Ana Díaz-Rubio, Sergei Tretyakov
Metasurfaces have shown unprecedented possibilities for wavefront manipulation of waves. The research efforts have been focused on the development of metasurfaces that perform a sp…
Independent Control of Multiple Channels in Metasurface Devices
Xuchen Wang, Ana Díaz-Rubio, Sergei A. Tretyakov
In analogy with electromagnetic networks which connect multiple input-output ports, metasurfaces can be considered as multi-port devices capable of providing different functionalit…
Omega-bianisotropic metasurface for converting a propagating wave into a surface wave
Vladislav Popov, Ana Díaz-Rubio, Viktar Asadchy +4
Although a rigorous theoretical ground on metasurfaces has been established in the recent years on the basis of the equivalence principle, the majority of metasurfaces for converti…
Perfect Generation of Angular Momentum with Cylindrical Bianisotropic Metasurfaces
Junfei Li, Ana Díaz-Rubio, Chen Shen +3
Recent advances in metasurfaces have shown the importance of controlling the bianisotropic response of the constituent meta-atoms for maximum efficiency wavefront transformation. U…
A Surface Impedance-Based Three-Channel Acoustic Metasurface Retroreflector
Chen Shen, Ana Díaz-Rubio, Junfei Li +1
We propose the design and measurement of an acoustic metasurface retroreflector that works at three discrete incident angles. An impedance model is developed such that for acoustic…
