Abstract:
Magnetic resonance is numerically investigated in a metallic metamaterial comprising rings and plates. It is found that a transmission band, instead of a stop band, results from the magnetic resonance as long as the electric field of the incident wave is polarized parallel to the ring plane, and thus it is an omnidirectional magnetic resonance transmission. We also observe an elimination phenomenon of the magnetic resonance transmission by tailoring the size of the plate, which implies a magnitude modulation of magnetic resonance. In addition, the equivalent LC circuit model is applied to analyze the geometry dependence of the magnetic resonance frequency, which is consistent with the numerical results by parametric simulations on the structural variations.

If, however, the bob is a slotted metal plate, the magnet produces a much smaller effect. When a slotted metal plate enters the field, an emf is induced by the change in flux; however, it is less effective because the slots limit the...

Diamagnetism was discovered by Anton Brugmans in 1778 when he observed that bismuth gets repelled by magnetic fields, thus theorizing that diamagnets get repelled by magnets.
