n. (context chiefly attributive English) A method for simulating the interaction of an electron beam with matter, used in high-resolution transmission electron microscopy images.
Wikipedia
The multislice algorithm is a method for the simulation of the interaction of an electron beam with matter, including all multiple elastic scattering effects. The method is reviewed in the book by Cowley. The algorithm is used in the simulation of high resolution Transmission electron microscopy micrographs, and serves as a useful tool for analyzing experimental images. Here we describe relevant background information, the theoretical basis of the technique, approximations used, and several software packages that implement this technique. Moreover, we delineate some of the advantages and limitations of the technique and important considerations that need to be taken into account for real-world use.
