Physicists at the University of Southampton have tested and proven a 50-year-old theory for the first time using electro-magnetic waves. They have shown that the energy of waves can be increased by ...

Wave-topology interactions underlie phenomena across physics, from condensed matter to cosmology, with the Aharonov-Bohm (AB) effect providing a paradigmatic example. Classical analogues in fluid ...

Understanding the mechanisms underlying a stable polarization at the surface of ferroelectric thin films is of particular importance both from a fundamental point of view and to achieve control of the ...

Maximum transmission efficiency occurs when the load impedance matches the generator impedance. Engineers do this to eliminate standing waves, which can severely damage equipment. Transmission lines ...
