Time-varying components for enhancing wireless transfer of power and information
Prasad Jayathurathnage, Fu Liu, Mohammad S. Mirmoosa +3
Temporal modulation of components of electromagnetic systems provides an exceptional opportunity to engineer the response of those systems in a desired fashion, both in the time an…
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…
Nonreciprocity in Bianisotropic Systems with Uniform Time Modulation
Xuchen Wang, Grigorii Ptitcyn, Ana Díaz-Rubio +4
Physical systems with material properties modulated in time provide versatile routes for designing magnetless nonreciprocal devices. Traditionally, nonreciprocity in such systems i…
Theory and Design of Multifunctional Space-Time Metasurfaces
Xuchen Wang, Ana Diaz-Rubio, Huanan Li +2
Integrating multiple functionalities into a single metasurface is becoming of great interest for future intelligent communication systems. While such devices have been extensively…
Graphene-based Perfect Absorbers: Systematic Design and High Tunability
Xuchen Wang, Sergei A. Tretyakov
Experimental realization of efficient graphene-based absorbers is a challenging task due to the low carrier mobility in processed graphene. In this paper, we circumvent this proble…
Graphene-Based Tunable Metasurface for All-angle Perfect Absorption
Xu-Chen Wang, Sergei A. Tretyakov
Motivated by the idea of smart metasurfaces, we will demonstrate a graphene-based tunable absorber in which perfect absorption can be achieved for all angles of incidence, only by…
