Analytical modeling shows that droplets ≤1 μm in size can be completely evaporated over time scales typical for cathodic arc deposition systems. It is shown that small microdroplets evaporate more intensively. The lower limit working points in terms of plasma electron density, and the electron energy and density of the injected energetic electrons required for droplet evaporation are found.   021120261031202516405https://creativecommons.org/licenses/by/4.0https://creativecommons.org/licenses/by/4.0https://creativecommons.org/licenses/by/4.010.5281/zenodo.18588455https://zenodo.org/record/17423193https://zenodo.org/record/1690928610.46298/ops.16405http://ops.episciences.org/16405https://zenodo.org/api/records/18588455/files/OPS_article_16405.pdf/contenthttps://zenodo.org/api/records/18588455/files/OPS_article_16405.pdf/content
