Superparamagnetic Fe3O4 colloids with highly charged surfaces have been assembled into ordered structures in water in response to external magnetic fields. The colloids form chainlike structures with ...

In this study, a two-dimensional beam expansion method with a volume holographic optical element is proposed. The volume holographic optical element diffracts cylindrical waves to plane waves with ...

This manuscript presents a mini review on the potential new application of geocell in the mitigation of ground vibration. An effort has been made to provide ...

Hi, I really like the existing plotting functions. The only thing is that I am looking for a way to export these "wavefront planes" as pure images without the matplotlib axes etc. So basically what ...

Putting a pinhole in front of the laser is typically done to approximate a point source spherical wave. The circular apodization of the pinhole really diffracts to form an Airy disk in the far field, ...

Crystallography databases hunt for fraudulent structures By working with journals and crystallographers, databases aim to catch fraud earlier ...

This grating diffracts the m = 1 order image in the y direction as a function of wavelength, creating a hyperspectral image with as many as 2,560 spectra captured simultaneously (i.e. one spectrum per ...

An algorithm to derive the diffraction coefficient for a surface wave that diffracts at the corner of a semi-infinite dielectric slab is proposed. Using the equivalence principle the dielectric slab ...

When sunlight hits the clouds just right, the light diffracts through them, creating a rainbow-like effect that is breathtaking. These new photographs were captured by amateur photographer ...

A team of physicists has recreated a classic experiment in particle physics with a dimensional twist, by performing it in time instead of just space. In the process, they showcased the utility of ...
