From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits

Advanced Science, EarlyView.
This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Ultra‐High Isolation Decoupling and Matching Network for mmWave Antennas in Near‐Range FMCW Radars

Microwave and Optical Technology Letters, Volume 68, Issue 10, October 2026.
ABSTRACT A decoupling and matching network (DMN) based on substrate integrated coaxial line technique is proposed to suppress the mutual coupling between a pair of transmitting and receiving antennas operating at 35 GHz. The distorted radiation patterns, typically observed in closely spaced antennas, were improved by introducing carefully designed ...

Reconfigurable Terahertz Multi‐Harmonic Dual‐Combs

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Terahertz dual‐comb spectroscopy requires precise control of repetition frequencies. A reconfigurable dual‐comb system is realized on a single self‐detected quantum cascade laser platform, where harmonic order serves as a new tuning parameter. Switching among fundamental and harmonic states enables flexible multi‐heterodyne down‐conversion without ...
