Metasurfaces as optically thin composite layers can be modeled as electric and magnetic
surface current sheets flowing in the layer volume in the metasurface plane. In the most …

The physics and applications of a broad class of artificial electromagnetic materials
composed of lattices of aligned metal rods embedded in a dielectric matrix are reviewed …

In this article, we present the theoretical considerations and the design evolution of a proof-
of-concept reconfigurable metasurface, primarily used as a tunable microwave absorber, but …

In view of extremely challenging requirements on the design and optimization of future
mobile communication systems, researchers are considering the possibilities of creating …

An equivalent circuit (EC) model for the frequency-selective surfaces (FSSs) comprising
anisotropic elements is presented. The periodic surface is initially simulated with an arbitrary …

This work theoretically and experimentally studies metasurfaces with spatially discrete,
traveling-wave modulation (SDTWM). A representative metasurface is considered consisting …

In this paper, a class of integrated metasurface (MS)-based planar antennas are proposed,
which are fed by monopoles operating below their fundamental modes. Various …

We propose an effective route to fully control the phase of plane waves reflected from
electrically (optically) thin composite sheets. This becomes possible using engineered …

A simple quasistatic model applicable to a wide class of wire media is developed that
explains strong nonlocality in the dielectric response of wire media in the very long …

The application of UHF radio-frequency identification (RFID) systems is rapidly increasing.
However, the reliability of indoor telecommunication is adversely affected by multiple …
