A circular polarization (CP) folded reflectarray antenna is proposed at the 30 GHz band. A five-layered circular polarization selective metasurface (CPSM) is introduced to realize the path folding for ...

We present analytical formulations, based on a coulombian approach, of the magnetic field created by permanent-magnet rings. For axially magnetized magnets, we establish the expressions for the three ...

Once the exploration efforts of rare earth bear viable fruit, the authorities can opt for a price discovery model. This will ...

Theoretical work has highlighted the potential of using devices in which spin-polarized carries are injected in single molecular magnets, and a few experiments have shown promising results. The ...
