The forum discussion centers on a groundbreaking device that functions as a diode for magnetic fields, as reported in a Phys.org article. This innovation challenges traditional physics principles, specifically the 19th-century laws governing magnetic fields. Participants express skepticism regarding the feasibility of such a device, noting the existence of one-way electromagnetic devices in RF Engineering, such as circulators and isolators, which rely on dissipative elements and non-linearity.
PREREQUISITESPhysicists, electrical engineers, and researchers interested in advancements in magnetic field technology and RF Engineering applications.
Sounds interesting but it should be treated with care without a more full description. There are 'one way' EN devices in RF Engineering (Circulators and Isolators) which force EM waves to 'go one way' but they involve dissipative elements and non-linearity.CWatters said:Couldn't see this news posted elsewhere. Sound too good to be true?...

I haven't read their paper yet.
