Negative permeability in magnetostatics and its experimental demonstration
Negative permeability in magnetostatics and its experimental demonstration
The control of magnetic fields, essential for our science and technology, is currently achieved by magnetic materials with positive permeability, including ferromagnetic, paramagnetic, and diamagnetic types. Here we introduce materials with negative static permeability as a new paradigm for manipulating magnetic fields. As a first step, we extend the solutions …
