Now that we have explored light waves, we can dive more in depth into polarization. In how to describe light, we mentioned that sunlight is a form of unpolarized light or natural light. But what ...

Domain walls are topological defects that occur at symmetry-breaking phase transitions. Although domain walls have been intensively studied in ferromagnetic materials, where they nucleate at the ...

Fig. 1 (a) Schematic of a PM that consists of two nanobeam cavities. (b) Normalized profile of the electric field (Ex at left and Ey at right) for the S and AS mode Polarization is an intrinsic ...

Adaptive optics (AO) is a technique used for real-time correction of phase aberrations by employing feedback to adjust the optical system. Polarization aberrations represent another significant type ...

So I've been familiar with the basics of polarization since forever, but I recently realized circular polarization is a mystery to me. I've heard of it in conjunction with eg satellite broadcasts, but ...

Sliding ferroelectrics are a type of two-dimensional (2D) material realized by stacking nonpolar monolayers (atom-thick layers that lack an electric dipole). When these individual layers are stacked, ...

New research helps understand movement of electrons in two-dimensional systems. The movement of thousands of negatively charged atomic particles -- electrons -- makes modern electronics tick. Yet, ...

Credit card-thick, flat lenses with tunable features based on graphene and gold have been developed by a partnership of Korean- and UK-based researchers. They say that such optical devices “could ...

When the Harvard-Smithsonian Center for Astrophysics announced a press conference for a "Major Discovery" (capital letters in the original e-mail) involving an unspecified experiment, rumors began to ...

Holographic images: the two figures on the left are two holographic images produced by a leaky-wave metasurface at two different distances from the device surface. The other figures are distinct ...
