New surface waves in gradient-index metasurfacesLei Zhou
Recently, metasurfaces have been proven to be effective and compact devices for the design of arbitrary wavefronts. Metasurfaces are planar metamaterials with a subwavelength thickness that allows wavefront shaping by introducing in-plane variations, namely, gradients, in the spatial wave response of...
for example, the control of freely propagating waves (PWs; refs1,2,3,4,5,6) and surface waves (SWs; refs7,8,9,10) has separately become possible using transformation optics and metamaterials, a bridge linking both propagation types has not yet been found. Such a device has particular...

In this study, we show that fine manipulation of sound waves can be achieved through lossy acoustic gradient-index metasurfaces by utilizing the energy losses. This work, provides a practical route for achieving independent and arbitrary modulation of the amplitude and phase of sound. We ...
In this paper, a method to transfer and control multi-beam reflections from a normal incident wave using a gradient-index metasurface is presented. By tuning properly the phase difference over the gradient-index metasurface, multi-beam anomalous reflections can be achieved, where the beam wavefront...
This thesis proposes a proof of feasibility for a metamaterial infrared detector containing an anti-reflective coating with various geometrically varying periodic metasurfaces, a gradient-indexed dielectric multilayer for near-perfect longpass filtering, and a gradient index of refraction (GRIN) metalens ...
In cases where the wave is confined to a plane, an all-metal metasurface lens realized in a textured parallel waveguide proves more efficient21. An interesting alternative are geodesic lenses that support either a surface wave22 or the transverse electromagnetic (TEM) wave in a doubly-curved ...
