WAVE: Combining diffraction and lens aberrations

WAVE computes the current density distributions in electron beams using a wave optical treatment, with Kirchhoff's diffraction integral.  In this software package, the following four effects are taken into account: diffraction; spherical aberration; chromatic aberration; and  demagnification of the Gaussian

image of the source.  Five programs are included in this software package.

WAVE1 computes the beam current density distribution with the combined effects of diffraction and spherical aberration (monochromatic point spread function).

WAVE2 computes the beam current density distribution with the combined effects of diffraction, spherical aberration and chromatic aberration (polychromatic point spread function).

WAVE3 computes the beam current density distribution with the combined effects of diffraction, spherical aberration, chromatic aberration and demagnified Gaussian image of the source (overall current density distribution with an extended source).

WAVEP1 plots the beam current density distribution from the results computed by Programs WAVE1, WAVE2 and WAVE3.

WAVEP2plots the normalized beam current density distribution from the results computed by Programs WAVE1, WAVE2 and WAVE3.
