Boston University researchers, Xin Zhang, a professor at the College of Engineering, and Reza Ghaffarivardavagh, a Ph.D. student in the Department of Mechanical Engineering, released a paper in Physical Review B demonstrating ...
Metasurfaces are two-dimensional (2-D) metamaterials that can control scattering waves of a light beam. Their applications include thin-sheet polarizers, beam splitters, beam steerers and lenses. These structures can control ...
Researchers at Duke University and Aalto University (Finland) have constructed a "meta-mirror" device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking ...
Researchers at Duke University have discovered that a perfect absorber of electromagnetic waves they described in a 2017 paper can easily be tweaked into a sort of "time-reversed laser" known as a coherent perfect absorber ...
Complex, three-dimensional (3-D) structures are regularly constructed using a reliable commercial method of 3-D laser micro- and nanoprinting. In a recent study, Frederik Mayer and co-workers in Germany and Australia have ...
Hyperbolic metamaterials are artificially made structures that can be formed by depositing alternating thin layers of a conductor such as silver or graphene onto a substrate. One of their special abilities is supporting the ...
Quasiparticles that behave like massless fermions, known as Weyl fermions, have been at the center of a string of exciting findings in condensed matter physics in recent years. The group of physicist Sebastian Huber at ETH ...
As below, so above. That seems to be an operating principle for molecules that start with a basic chirality—or "handed-ness"—and pass it on as they combine into larger structures.
By bombarding an ultrathin semiconductor sandwich with powerful laser pulses, physicists at the University of California, Riverside, have created the first "electron liquid" at room temperature.
In work that provides insights for several areas of wave physics, including Maxwell electromagnetism, topological quantum states, and plasmonics/metamaterials, scientists have shown that the well-known surface electromagnetic ...
