The novel flexible-antenna technology, referred to as pinching-antennas, has recently attracted significant academic interest. By embedding separate dielectric materials, these antennas can be activated at arbitrary points along waveguides, facilitating the flexible configuration of large-scale path loss. This paper co...

This paper proposes a dual aerial active reconfigurable intelligent surface (ARIS)-assisted non-orthogonal multiple access (NOMA)-based integrated terrestrial and non-terrestrial networks (ITNTN), where UAV-mounted and HAP-mounted ARISs assist terrestrial and satellite users, respectively. We formulate an average sum-r...

The emergence of sixth-generation (6G) wireless networks demands unprecedented improvements in data rates, connectivity, and energy-efficiency (EE), making the terahertz (THz) band a key enabler due to its vast, underutilized spectrum and high spatial resolution. This survey stands apart from previous studies by provid...

This paper proposes a pinching antenna system (PASS)-assisted downlink quadrature rate-splitting multiple access (Q-RSMA)-based integrated sensing and communication (PASS-QRSMA-ISAC) framework for simultaneously supporting multi-user communication and target sensing. In the proposed framework, multiple pinching antenna...

This letter investigates the covert performance of a pinching-antenna system (PASS) assisted non-orthogonal multiple access (NOMA) network in a heterogeneous propagation environment. In the considered setup, a pinching antenna is deployed along a dielectric waveguide to flexibly control the radiation position and enhan...
The proposed architecture achieves superior radar beampattern control and favorable energy efficiency-performance trade-offs, establishing active BD-RIS as a promising enabler for sensing-aware, energy-efficient, and high-capacity 6G DFRC networks.
