When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of grooves ...

Materials science is an interdisciplinary field concerned with the understanding and application of the properties of matter. Materials scientists study the connections between the underlying ...

Quantum physics overturned classical ideas by showing that matter behaves very differently at the smallest scales. One of its most surprising discoveries was wave-particle duality, the idea that ...

Abstract: The two-frequency tunable resonance effect for electron beam diffraction radiation flowing over a large finite grating made of circular graphene nanotubes is considered. The excitation field ...

Abstract: To effectively address the issues of being unable to conduct large-scale, extensive network application experiments due to limited laboratory equipment and the failure of existing network ...
