An electromagnetic wave or signal traveling from “here” to “there” has an electrostatic field component that we call its E-field and whose direction we assign as the signal’s polarity. Often, the ...

Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images. Yet controlling these properties independently ...

Lead-based B-site complex perovskites, also referred to as “relaxors,” exhibit large dielectric responses due to their complex structures. Understanding their atomic arrangements and inhomogeneous ...

In a study published in Nano Letters, researchers demonstrated that light can change the electric polarization within the domains of a relaxor material in just trillionths of a second. Depiction of ...
