Linear polarization holography
In conventional holography, the hologram is formed by recording the interference fringes of two coherent beams using a photosensitive material. The amplitude and phase information of the original signal wave can be reconstructed correctly when readin.....»»
Scientists" political donations reflect polarization in academia—with implications for the public"s trust in science
People who lean left politically reported an increase in trust in scientists during the COVID-19 pandemic, while those who lean right politically reported much lower levels of trust in scientists. This polarization around scientific issues—from COV.....»»
Why our news consumption might be more worrisome than misinformation
Misinformation and echo chambers are often used to explain polarization and political divides between people. New research, however, finds there is another factor we should worry about, namely our online consumption of quality news, or exactly the la.....»»
Taiwanese suppliers cautious toward smartphone-to-satellite communication
With Starlink and satellite communication network growing in popularity and importance, Taiwan-based low-earth orbit (LEO) system integrators observed that the LEO satellite sector is not experiencing exponential growth, but linear growth. Neverthele.....»»
Polychromatic full-polarization control in mid-infrared light
Mid-wavelength infrared (MWIR) as one of the most important transparent atmosphere windows is less sensitive to interference from the background emission of the sun, providing a high-transmission zone for the finger-print spectra of various materials.....»»
Researchers develop clever algorithm to improve our understanding of particle beams in accelerators
Whenever SLAC National Accelerator Laboratory's linear accelerator is on, packs of around a billion electrons each travel together at nearly the speed of light through metal piping. These electron bunches form the accelerator's particle beam, which i.....»»

A general theory to realize bilayer stacking ferroelectricity
Two-dimensional (2D) ferroelectrics, planar materials that have a spontaneous and reversible electric polarization, are extremely rare and yet could be extremely advantageous for the development of new nanoelectronics. Due to their ferroelectric prop.....»»
New approach to developing efficient, high-precision 3D light shapers
Modern-day technologies like optical computing, integrated photonics, and digital holography require light signals to be manipulated in three dimensions. To achieve this, it is necessary to be able to shape and guide the flow of light according to it.....»»
New light sheet holography overcomes the depth perception challenge in 3D holograms
Holography—the use of light projection to display images—can be used to construct holograms, which are three-dimensional structures of light that depict true-to-life objects and scenes. While today's technologies can't yet produce the incredibly.....»»
Multi-foci metalens for spectra and polarization ellipticity recognition and reconstruction
As fundamental properties of light, spectra and polarization carry vital information concerning the propagation of light waves. For example, spectral imaging can reflect the material composition of objects, while polarized imaging contains informatio.....»»
Bringing angular momentum to holograms and metasurfaces
Holography, invented by Gabor, provides an approach for recording and reconstructing the complete information (i.e. intensity and phase) of the light from an object. Since its invention, holographic-related technologies have been widely applied in nu.....»»
Assessing the sea surface temperature relationship in shallow marine waters
In a study published in the journal Science China Earth Sciences, researchers led by Dr. Mengyuan Wang (School of Marine Sciences, Sun Yat-sen University) proposed a non-linear regression of UK'37–SST for samples collected from the specific environ.....»»
A new approach to measuring and understanding multidirectional polarization
Germany, India, Mexico, and Spain. As multiparty democracies, these countries present a more complex picture of what brings people together—or divides them. Using social media data, a group of researchers proposes a novel approach to measuring pola.....»»
Bees follow linear landmarks to find their way home, just like the first pilots
Scientists have shown that honeybees retain a memory of the dominant linear landscape elements in their home area like channels, roads, and boundaries. When transported to an unfamiliar area, they seek out local elements of this kind, compare their l.....»»
Roads and power lines put primates in danger: South African data adds to the real picture
About 25 million kilometers of new roads are expected to be built around the world by 2050. Along with power lines and railways, roads cut through the landscape everywhere, disrupting ecosystems. This linear infrastructure prevents animals from movin.....»»
New method for deriving approximate linear equations to complicated nonlinear problems
Researchers at the University of Tsukuba have created a new method for deriving approximate linear equations to complicated nonlinear problems. Using simulation results, they show that the model derived using their proposed pseudo-linearization appro.....»»
From transient to eternal: Probing equilibrium correlations by ramping dynamics
