A Shared-Aperture Dual-Band sub-6 GHz and mmWave Reconfigurable Intelligent Surface With Independent Operation [PDF]

open access: yesarXiv
A novel dual-band reconfigurable intelligent surface (DBI-RIS) design that combines the functionalities of millimeter-wave (mmWave) and sub-6 GHz bands within a single aperture is proposed. This design aims to bridge the gap between current single-band reconfigurable intelligent surfaces (RISs) and wireless systems utilizing sub-6 GHz and mmWave bands ...

Evaluation of Two Tension Sensors for Cable‐Driven Parallel Manipulators

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Cable‐driven parallel manipulators (CDPMs) constitute a class of parallel robots in which the frame is connected to the end‐effector through a set of cables. The weight reduction achieved by replacing rigid links with cables, along with their exceptionally large workspace, makes CDPMs suitable for applications such as positioning devices ...
