Nanophotonics, Volume 15, Issue 17, 11 September 2026.We demonstrate a VO2‐based transmissive reconfigurable intelligent surface for indoor millimeter‐wave communication. The TRIS replaces conventional PIN and varactor diodes with geometrically tailored VO2 switches, enabling transmitted phase control through phase‐transition‐based switching.

Measurement of Error Vector Magnitude (EVM) to Characterize the Impairment of the Tracking and Data Relay Satellite (TDRS) Channel [PDF]
, 2016 A digital signal is transmitted via a carrier wave, it demodulates at a receiver, and locates at an ideal constellation point. However, noise distortion, carrier leakage, and phase noise can force a signal to divert from its ideal position to a new ...

Ultralow‐Dispersion Silicon THz Photonic Crystal Interconnects for Multichannel Datalinks
Advanced Materials, Volume 38, Issue 48, 26 August 2026.An all‐silicon terahertz photonic crystal waveguide interconnect enables 452 Gbps aggregate data transfer through seven complex‐modulated channels. By revealing the impact of ultralow dispersion on link performance and achieving a record interconnect figure of merit, the work advances centimeter‐scale THz on‐chip communication for future data‐centre ...

Nanophotonics, Volume 15, Issue 14, 27 July 2026.This study demonstrates, for the first time, a 3D volumetric cylindrical vector beam (CVB) multicasting architecture that employs multichannel array modes with an operational dimension of 3 × 3 × 5 as information carriers. This approach offers substantial potential for high‐capacity information dissemination in mode‐multiplexed communication networks ...

EVM Prediction for Massive MIMO [PDF]
, 2019 Signal to interference plus noise ratio (SINR) is a widely common performance metric used in the majority of massive multiple-input, multiple-output (Ma-MIMO) research. This metric requires prior knowledge of the user channel vectors and the interference

EVM-Constrained and Mask-Compliant MIMO-OFDM Spectral Precoding
, 2021 Spectral precoding is a promising technique to suppress out-of-band emissions and comply with leakage constraints over adjacent frequency channels and with mask requirements on the unwanted emissions.

Assessment of Transient EMI Impact on LTE Communications Using EVM & PAPR
IEEE Access, 2020 The brief contact losses between the pantograph and the catenary in high-speed trains create transient interferences, which extend to the frequency bands used by telecommunication systems.

Lipid and Foam Cell Accumulation as Novel Pathological Features of Benign Prostatic Hyperplasia
The Prostate, Volume 86, Issue 10, Page 1157-1169, July 2026.ABSTRACT Background Benign prostatic hyperplasia (BPH) encompasses a heterogeneous set of pathological processes that instigate lower urinary tract symptoms (LUTS). Using a mouse model of steroid hormone imbalance–induced lower urinary tract dysfunction, we identified luminal lipid‐laden foamy macrophages, although their presence and contribution to ...
