Pouvoir de transmission d'un système fente–fente en optique corpusculaire

Abstract

A method to calculate the transmission properties of a slit–slit system in electronic optics is described. It includes the following steps: calculation of the electric field between the electrodes, calculation of the electron trajectories point by point as a function of the initial conditions, and finally counting of the electrons which reach the second slit. Calculated and measured values of the transmission efficiency for usual geometrical dimensions of this system are presented.
