A detector of gravitational waves based on coupled microwave cavities [PDF]

, 2002
Since 1978 superconducting coupled cavities have been proposed as sensitive detector of gravitational waves. The interaction of the gravitational wave with the cavity walls, and the resulting motion, induces the transition of some electromagnetic energy ...

MXene/PEDOT Functional Coatings on Flexible Microelectrode Arrays for Multianalyte In Vivo Neurochemical Sensing and Electrophysiology

Advanced Functional Materials, EarlyView.
A MXene/PEDOT coating enables multimodal functionality and dual‐analyte detection of dopamine and serotonin in flexible microelectrode arrays while enhancing electrophysiological recording quality. The anti‐fouling, low‐impedance interface overcomes key limitations of conventional coatings, providing a robust and versatile platform to investigate the ...

A Non‐Reciprocal Architected Porous Medium

Advanced Functional Materials, EarlyView.
ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

Reliability Evaluation and Failure Simulation Research of the PIN Limiter in Complex Electromagnetic Environments

IEEE Access
As the electromagnetic environment becomes increasingly complex, high-power microwave (HPM) pulses with different parameters are superimposed and coupled into RF receivers. Consequently, the PIN limiter at the front end often fails due to excessive input
