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 ...

Schematic of chiral terahertz generation and control: A femtosecond laser interacts with a patterned spintronic emitter, producing elliptically or circularly polarized terahertz waves. Rotating the ...

Terahertz (THz) waves are located between microwaves and infrared light in the electromagnetic spectrum. They can pass through many materials without causing damage, making them useful for security ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Independent manipulations of various properties of EM waves are crucially required in a wide range of ...

In the theory of the propagation of radio waves through a homogeneous ionized medium it is well known that 'characteristic' waves, sometimes called the 'ordinary' and 'extraordinary' waves, are ...

Polarizing film has an axis (in our diagrams we depict its direction with lines on the film), and the film allows passage of light that is oscillating parallel to the axis. You can think of light as ...

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, ...

Gravitational waves from inflation generate a faint but distinctive twisting pattern in the polarization of the cosmic microwave background, known as a "curl" or B-mode pattern. For the density ...
