The High Power Pulsed Magnetron Sputtering (HPPMS) technique has gained substantial interest in both academic and industrial environments. Its most valuable features are: the high ionization degree of the sputtered material it allows to achieve, and the improved quality of the film deposited even on complex-shaped substrates. Several are the issues related to the modeling of a HPPMS: dense plasma in a strong magnetic filed, high ionization degree of the sputtered material, strong gas rarefaction and anomalous electron transport due to instabilities. In this paper, we present a simplified analytic approach to address what we believe are the most fundamental physical phenomena and some preliminary results obtained by means of hybrid models.
