An emitter near a surface induces an image dipole that can modify the observed emission intensity and radiation pattern. These image-dipole effects are generally not taken into account in ...

Achieving high-energy density remains a key objective for advanced energy storage systems. However, challenges, such as poor cathode conductivity, anode dendrite formation, polysulfide shuttling, and ...

Physicists are closer to finding out if the electron is a point charge or whether it has an internal distribution of charge known as an electric dipole moment. For the first time, Ed Hinds and ...

A dipole antenna is easy, right? Two wires, each a quarter wavelength long, emanate from a coax or other feedline. Unless it is an off-center dipole. The length is still the same, but you move the ...

Incompatible moments A spinning charge (left) acts like a loop of current to produce a magnetic dipole moment (blue arrow). Distorting the electron's charge distribution (middle) produces an electric ...

Do electrons have a fourth property in addition to mass, charge and spin, as popular physics theories such as supersymmetry predict? Researchers from Germany, the Czech Republic and the United States ...

One of the most peculiar things about the Universe is how quickly the Milky Way appears to be moving. Despite having mapped out the cosmic masses nearby to unprecedented accuracy, there still doesn't ...
