The microwave absorption properties of soft magnetic materials in frequency up to 40 GHz

AIP Advances, 2023
With the continuous development of communication technology, the microwave frequency used has been extended to 24∼30 GHz or even higher. Thus, for the research on microwave absorption materials, the commonly used 2∼18 GHz frequency range might no longer ...

Shape programmable magnetic pixel soft robot

Heliyon, 2022
Magnetic soft robots (MSRs) can achieve controllable shape-morphing by magnetic programming to the magnetic elastomer. However, the magnetization profile is usually implemented on a continuous region and is unchangeable.
