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 ...
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 ...
A new publication from Opto-Electronic Science; DOI 10.29026/oes.2023.220026 considers multi-foci metalens for spectra and polarization ellipticity recognition and reconstruction. As fundamental ...
Researchers have produced a record-thin optical quarter-waveplate from the two-dimensional material niobium oxychloride (NbOCl2), measuring roughly 269 nanometers thick and operating at a wavelength ...
Schematic diagram of the beam homogenization method based on polarization-encoded metasurface. QWP quarter-wave plate, PD photoelectric detection. The inset in the upper right corner illustrates the ...
Relaxor–ferroelectric materials are high-performance ultrasound generation elements exhibiting large dielectric responses owing to their complex structures. Recently, researchers from Japan made use ...
