The terahertz (THz) frequency band has recently attracted considerable attention in wireless
communications as potential candidate for providing the necessary high bandwidth for …

The design of Reconfigurable Intelligent Surfaces (RISs) is largely based on treating the RIS
as an infinitely large, continuous surface that steers an incident plane wave towards the …

A Reconfigurable Intelligent Surface (RIS) redirects and possibly modifies the properties of
incident waves, with the aim to restore non-line-of-sight communication links. Composed of …

A reconfigurable microwave reflectarray metasurface (MS) is investigated for beamforming
applications. The reflected beam direction is changed by applying external dc voltages …

In the proposed work presented to improve the strength of wireless networks, to ensure
efficient utilization of the bandwidth. Reconfigurable Intelligent Surfaces (RIS) provides an …
