Electromagnetic characterization of bianisotropic metasurfaces on refractive substrates: General theoretical framework
M. Albooyeh, S. Tretyakov, C. Simovski
We present a general methodology for electromagnetic homogenization and characterization of bianisotropic metasurfaces formed by regular or random arrangements of small arbitrary i…
Modeling of Isotropic Backward-Wave Materials Composed of Resonant Spheres
L. Jylha, I. Kolmakov, S. Maslovski +1
A possibility to realize isotropic artificial backward-wave materials is theoretically analyzed. An improved mixing rule for the effective permittivity of a composite material cons…
Three-dimensional isotropic perfect lens based on LC-loaded transmission lines
P. Alitalo, S. Maslovski, S. Tretyakov
An isotropic three-dimentional perfect lens based on cubic meshes of interconnected transmission lines and bulk loads is proposed. The lens is formed by a slab of a loaded mesh pla…
Reradiation and Scattering from a Reconfigurable Intelligent Surface: A General Macroscopic Model
V. Degli-Esposti, E. M. Vitucci, M. Di Renzo +1
Reconfigurable Intelligent Surfaces (RISs) have attracted major attention in the last few years, thanks to their useful characteristics. An RIS is a nearly passive thin surface tha…
Reconfigurable Intelligent Surfaces vs. Relaying: Differences, Similarities, and Performance Comparison
M. Di Renzo, K. Ntontin, J. Song +12
Reconfigurable intelligent surfaces (RISs) have the potential of realizing the emerging concept of smart radio environments by leveraging the unique properties of meta-surfaces. In…
Super-Planckian thermal emission from a hyperlens
C. Simovski, S. Maslovski, S. Tretyakov +3
We suggest and theoretically explore a possibility to strongly enhance the steady thermal radiation of a small thermal emitter using an infrared hyperlens. The hyperbolic metamater…
