Loss-induced performance limits of all-dielectric metasurfaces for terahertz sensing
J. A. Álvarez-Sanchis, B. Vidal, S. A. Tretyakov +1
Metasurfaces providing resonances arising from quasi-bound states in the continuum have been proposed as sensors in the THz band due to the existence of strong resonances character…
Subwavelength Focusing by Engineered Power Flow-Conformal Metamirrors
Hamidreza Taghvaee, Fu Liu, Ana Díaz-Rubio +1
Many advances in reflective metasurfaces have been made during the last few years, implementing efficient manipulations of wavefronts, especially for plane waves. Despite numerous…
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

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…
Transmission magnitude and phase control for polarization-preserving reflectionless metasurfaces
Do-Hoon Kwon, Grigorii Ptitcyn, Ana Díaz-Rubio +1
For transmissive applications of electromagnetic metasurfaces, an array of subwavelength Huygens' metaatoms are typically used to eliminate reflection and achieve a high transmissi…
Near-Perfect Conversion of a Propagating Plane Wave into a Surface Wave Using Metasurfaces
Svetlana N. Tcvetkova, Do-Hoon Kwon, Ana Díaz-Rubio +1
In this paper, theoretical and numerical studies of perfect/nearly-perfect conversion of a plane wave into a surface wave are presented. The problem of determining the electromagne…
Experimental evidence of total absorption by a thin absorbing layer deposited on a patterned metallic surface
