An X-ray beam is an electromagnetic wave characterized by an electric field vibrating at constant frequency, perpendicular to the direction of movement. This variation of the electric field gives electrons (charged particles) a sinusoidal change with time at the same frequency.

It can be shown that for small perturbations of a compressible fluid from rest, the pressure fluctuation p, density fluctuation p and velocity potential φ satisfy a scalar wave equation where c is the wave speed and q represents a distribution of sound sources.

The electron is a low mass, negatively charged particle. As such, it can easily be deflected by passing close to other electrons or the positive nucleus of an atom. These Coulomb (electrostatic) interactions cause the electron scattering which is the process that makes TEM feasible. We will also discuss how the wave nature of the electron gives rise to

Diffraction Scattering of Elementary Particles.
Il Nuovo Cimento, 1961The diffraction scattering of elementary particles is discussed. It is pointed out that there is a possibility of charge exchange diffraction scattering, except when it is inhibited at very high energy by the Pomerancuk theorem (1). The notion of inelastic diffraction scattering, recently discussed by Good and Walker is reformulated in relation to the ...

Light-scattering theory of diffraction
Journal of the Optical Society of America A, 2010Since diffraction is a scattering process in principle, light propagation through one aperture in a screen is discussed in the light-scattering theory. Through specific calculation, the expression of the electric field observed at an observation point is obtained and is used not only to explain why Kirchhoff's diffraction theory is a good approximation

These phenomena -scattering and diffraction-are of fundamental importance in micro wave antennas, for they underlie the formation of antenna patterns by reflectors and lenses. In the present chapter the theory of scattering and diffraction is developed with reference to general techniques; the specific problems associated with antenna patterns will be ...
