Uplink Cooperative NOMA for Cellular-Connected UAV
Weidong Mei,Rui Zhang +1 more
TL;DR: This paper proposes to apply the non-orthogonal multiple access (NOMA) technique to the uplink communication from a UAV to cellular BSs, under spectrum sharing with the existing ground users, and investigates the optimal design of cooperative NOMA and air-ground performance tradeoff.

Roughness losses and volume-current methods in photonic-crystal waveguides
Steven G. Johnson,Michelle L. Povinelli,Marin Soljacic,Aristeidis Karalis,Steven A. Jacobs,John D. Joannopoulos +5 more
TL;DR: In this article, a semi-analytical extension of the classic volume-current method to low-index contrast systems was proposed, which corrected a longstanding limitation of such methods to low index contrast systems (the classic method may be off by an order of magnitude in high contrast systems).
Journal ArticleDOI
Passive wireless antenna sensor for strain and crack sensing—electromagnetic modeling, simulation, and testing
TL;DR: In this article, a passive wireless antenna sensor designed for strain and crack sensing was investigated, where a radio frequency identification (RFID) chip was adopted for antenna signal modulation, so that a wireless reader can easily distinguish the backscattered sensor signal from unwanted environmental reflections.

Graphene nanoribbon based terahertz antenna on polyimide substrate
TL;DR: The proposed antenna consisting of graphene nano ribbon as radiating patch and also the ground plane separated by a 20 μm thin polyimide substrate has achieved the broad impedance bandwidth (>5%) in the band of operation.
Journal ArticleDOI
Increasing wireless channel capacity through MIMO systems employing co-located antennas
TL;DR: In this article, the authors reported similar increases in channel capacity obtained through the use of vector antennas consisting of co-located loops and dipoles, which can respond to more than one component of the EM field.
