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 ...

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 ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

With the development of different techniques for the synthesis of nanomaterials, researchers are constantly looking for a more precise instrument for their nanoscale characterization. X-ray ...

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 ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

[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 ...

This article explains the reason why so many manufacturers need to measure particle size and the reason behind laser diffraction being the method of choice. Different industries measure particle size ...
