A review on shear jamming [PDF]

open access: yesPhysics Reports, Volume 1038, 2 November 2023, Pages 1-18, 2023
Jamming is a ubiquitous phenomenon that appears in many soft matter systems, including granular materials, foams, colloidal suspensions, emulsions, polymers, and cells -- when jamming occurs, the system undergoes a transition from flow-like to solid-like states.

Beam-Domain Anti-Jamming Transmission for Downlink Massive MIMO Systems: A Stackelberg Game Perspective

open access: yesIEEE Transactions on Information Forensics and Security, 2021
In this paper, beam-domain (BD) anti-jamming transmission in a downlink massive multiple-input multiple-output (MIMO) system is investigated. A smart jammer with multiple antennas attempts to interfere with the signal reception of users with the desired ...

Study on the Effective Region of Active Decoy Jamming to SAR Based on Time-delay Doppler-shift Method

open access: yesLeida xuebao, 2013
The active decoy jamming to SAR based on the Time-Delay Doppler-Shift (TDDS) method takes effect in certain region. Proper utilization of jamming ensuring decoy quality is based on the study of the effective region. After the mathematical analysis of the

Interrupted-Sampling Repeater Jamming-Suppression Method Based on a Multi-Stages Multi-Domains Joint Anti-Jamming Depth Network

open access: yesRemote Sensing, 2022
Jamming will seriously affect the detection ability of radar, so it is essential to suppress the jamming of radar echoes. Interrupted-sampling repeater jamming (ISRJ) based on a digital-radio-frequency-memory (DRFM) device can generate false targets at ...

A Smart Noise Jamming Suppression Method Based on Atomic Dictionary Parameter Optimization Decomposition

open access: yesRemote Sensing, 2022
Smart noise jamming is a new jamming style against radar, which plays an important role in modern radar electronic warfare. In order to solve the complex problem of convolutional smart noise jamming suppression with different time delay and jamming ...

Incentive Jamming-Based Secure Routing in Decentralized Internet of Things

open access: yesIEEE Internet of Things Journal, 2021
This article focuses on the secure routing problem in the decentralized Internet of Things (IoT). We consider a typical decentralized IoT scenario composed of peer legitimate devices, unauthorized devices (eavesdroppers), and selfish helper jamming ...

Radar Anti-Jamming Decision-Making Method Based on DDPG-MADDPG Algorithm

open access: yesRemote Sensing, 2023
In the face of smart and varied jamming, intelligent radar anti-jamming technologies are urgently needed. Due to the variety of radar electronic counter-countermeasures (ECCMs), it is necessary to efficiently optimize ECCMs in the high-dimensional ...

Critically jammed [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
Diverse forms of matter around us can simply be classified as those that flow and those that don’t and exhibit rigidity, a resistance to deform when a force is applied. This elementary distinction informs our ability to comprehend their properties and to manipulate them. It is easy enough to pick up a spoon, a solid that pushes back against our fingers,
