STAR-RISs: Simultaneous Transmitting and Reflecting Reconfigurable Intelligent Surfaces
نویسندگان
چکیده
In this letter, simultaneous transmitting and reflecting reconfigurable intelligent surfaces (STAR-RISs) are studied. Compared with the conventional reflecting-only RISs, coverage of STAR-RISs is extended to 360 degrees via transmission reflection. A general hardware model for presented. Then, channel models proposed near-field far-field scenarios, based on which diversity gain analyzed compared that RISs. Numerical simulations provided verify analytical results demonstrate full order can be achieved both sides STAR-RIS.

Scattering in the Presence of a Reflecting and Transmitting Impurity
We investigate factorized scattering from a reflecting and transmitting impurity. Bulk scattering is non trivial, provided that the bulk scattering matrix depends separately on the spectral parameters of the colliding particles, and not only on their difference. We show that a specific extension of a boundary algebra encodes the underlying scattering theory. The total scattering operator is con...
متن کاملPerformance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward
In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...
متن کاملIntelligent Star Tracker
We describe our Intelligent Star Tracker System. The Intelligent Star Tracker System incorporates an adaptive optic catadioptric telescope in a silicon carbide housing. Leveraging off of our active optic technologies, the novel active pixel position sensors (APPS) enable wide dynamic range and allows simultaneous imagery of faint and bright stars in a single image. Moreover, the APPS, in conjun...
متن کاملLooking for Intelligent Reconfigurable Simulation
Simulation relates function to structure. Researching intelligence by simulating it to get to intelligent simulation demands the study of essential abstract structures: the human mind, the different types of hierarchies, and the simulation as relation between static and dynamic structures. Intelligence and Faith, as any other dichotomies, can converge together to integration, or can destroy eac...
متن کاملA Harbor Resonance Numerical Model with Reflecting, Absorbing and Transmitting Boundaries
Objective: To calculate wave response in an offshore or coastal harbor of arbitrary shape, this research develops a two-dimensional linear, inviscid, dispersive, hybrid finite element harbor resonance model using conservation of energy approach. Based on the mild-slope wave equation, the numerical model includes wave refraction, diffraction, and reflection. The model also incorporates the effec...
