Energy harvesting from power lines and magnetic fields has emerged as a promising avenue to complement conventional energy systems. This approach leverages ambient electromagnetic fields generated by ...

For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

Magnetic invisibility sounds simple in theory. Place the right materials around an object and magnetic fields flow around it as if nothing were there. Reality has been far messier. For nearly two ...
