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 ...

Reliably measuring the polarization state of light is crucial for various technological applications, ranging from optical communication to biomedical imaging. Yet conventional polarimeters are made ...

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 ...

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 ...
