The problem of the diffraction of electromagnetic waves by a circular aperture in an infinitely conducting planar screen is studied. Attention is focused chiefly on the low frequency end of the ...

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 ...

M. G. FOUSSERAU describes, in the Journal de Physique for October, a simple apparatus for viewing diffraction and interference phenomena, a modified form of which I have experimented on with success.
