Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

Using laser diffraction to determine sediment grain-size distributions is faster than sieving methods; however, the results of these analytical methods can often differ. Samples are generally only ...

The diffraction spikes so familiar to us in space images are an intrinsic property of the telescope. Reflecting telescopes have two mirrors: a large primary and a smaller secondary. Light hits the ...

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not ...

Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies.

The reduced dimensionality and broken symmetry of a surface endows it with unique physical and chemical properties that drastically differ from the bulk 1,2. Prominent surface-specific features ...

This is a preview. Log in through your library . Abstract A short-wave problem of reflection and radiation by an open end of a two-dimensional planar waveguide is studied. The incident mode is assumed ...

Test for echo: schematic diagram of an object to be imaged (blue blob) and illumination source (concentric circles) inside a randomly shaped cavity. The detector is represented by the two parallel ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...

[The Thought Emporium] has been fascinated by holograms for a long time, and in all sorts of different ways. His ultimate goal right now is to work up to creating holograms using chocolate, but along ...
