Beam scanning using microstrip line on biased ferrite [PDF]

, 1997
The beam scanning properties of a 2-element patch array fed by a microstrip reed situated on a ferrite substrate are presented. Biasing the ferrite changes the phase length or the microstrip line, scanning the beam by up to 40 degrees. The resulting scan

Dual‐Mode Magnetic Elastomer for On‐Demand Motion and Degradation

Advanced Functional Materials, Volume 36, Issue 49, 18 June 2026.
A dual‐mode magnetic elastomer is introduced, enabling DC field‐driven programmable actuation and AC field‐driven magnetothermal degradation. GHz‐range magnetic fields generate ultrafast heating of magnetic nanoparticles that activates cleavage of the silicone elastomer matrix.
