Investigating Dual-Frequency HPM Interference Effect on Communication System: Insights From LNA to SDR

open access: yesIEEE Access
In this paper, we investigate the impact of dual-frequency high-power microwave sources on communication systems. We begin by analyzing the nonlinear characteristics of the system using a fifth-order power series expansion.

Nanofillers Reinforcing Biopolymer Composites for Sustainable Food Packaging Applications: A State‐of‐the‐Art Review

open access: yesAdvanced Functional Materials, EarlyView.
Biopolymers are sustainable, biodegradable alternatives to petroleum‐based plastics for food packaging. Its adoption is often limited by poor mechanical strength, barrier properties, and improved thermal stability through the incorporation of nanofillers.

Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.

Research on Anti-Single-Frequency Interference Ability of Underwater Acoustic DSSS Communication System with Short-Period PN Sequences

open access: yesApplied Sciences
To address the inability to quantitatively analyze the performance of the direct sequence spread spectrum (DSSS) communication system in the presence of short-period pseudo-noise (PN) sequences, this study derives the interference components resulting ...

Ultraviolet–Visible Spin‐Resolved Chip‐Scale Spectroscopy

open access: yesAdvanced Functional Materials, EarlyView.
By harnessing phase, wavelength, and spin multiplexing, the proposed meta‐spectrometer enables spin‐resolved spectral analysis within a compact footprint. The presented dual‐band (320–450 nm) spin‐resolved meta‐spectrometer features enhance optical functionality, allowing for the simultaneous discrimination of spectral content and spin states of light ...
