LAMBDA Series XRifle Dynamic RIS
Reconfigurable Intelligent Surfaces (RIS) corresponds to a planar surface composed of unit-cells, whose properties can be controlled dynamically to ‘tune’ the incident wireless signals through reflection, refraction, focusing, collimation, modulation or absorption. RIS can be potentially deployed for both indoor and outdoor usage, including offices, airports, shopping centres, lamp posts and advertising billboards, and may take any shape or be integrated onto objects. Its characteristics may also result in low energy consumption, making RIS a sustainable technology solution.
RIS can be configured to operate at any part of the radio spectrum, including frequencies from 2.8GHz to 26GHz, and may harness tools from Artificial Intelligence (AI) and Machine Learning (ML) to enable systems operation and optimization. The scattering, absorption, reflection, and diffraction properties of the entire RIS can thereby be changed with time and controlled by software. An RIS can be utilized to support wireless communications as well as localization, sensing, and wireless power transfer. Can be utilized for improved communication, localization, and sensing.
The RIS can then receive signals from any direction from the halfspace towards which the RIS elements are facing and tuning the pattern of reflection coefficients over the elements to reradiate signals with the desired direction and beam shape.
