Now, a team led by Professor Sascha Feldmann at EPFL’s Laboratory for Energy Materials has developed a high-sensitivity, ...

EPFL scientists have developed a new technique that lets researchers watch, with unprecedented sensitivity, how materials ...

Polarization converter is firstly proposed with the functions of simultaneously converting a linear polarization (LP) and a circular polarization (CP) to its corresponding cross polarizations, and ...

Among them, the average or peak circular polarization fraction of 32 bursts exceed 50%. The highest degree of circular polarization reaches 90.9%, which is the new record in FRB observation.

Circular polarization is less susceptible to signal fading since the polarization most easily propagated is achieved whatever the intervening propagation environment might happen to be. In ham radio, ...

Three different pairs of orthogonal polarization states at three wavelengths are linear polarization at 3.0 μm, elliptical polarization (ellipse angle 30°) at 3.6 μm and circular polarization ...

We propose an active metasurface whose functionalities can be dynamically switched among linear-to-linear, linearto-elliptical, and linear-to-circular polarization conversions in a wideband. The ...

But suffice to say for linear polarization, δ = 0. Circular polarization implies δ= ±90° where right-hand circular polarization has +90° and left-hand circular polarization -90°. Elliptical ...

Light is an electromagnetic wave that can exist in a variety of polarization states, including linear, circular, and elliptical. These differ in the behavior of the oscillating electric field ...

Researchers have designed a metasurface that can be continuously tuned from linear to elliptical birefringence, opening up the entire space of polarization control with just one device. This ...

It is based on a simple cross-dipole FSS element. The linear to circular polarization is achieved by non-equally varying the length of dipoles in x and y directions. Both simulation and measured ...
