In this paper, an analytical model of the interaction between an intense electromagnetic pulse (EMP) and a spherical plasma discharge is presented. The study aims to provide a physical description of the nonlinear behavior of a plasma-based antenna subjected to an EMP during experimental illuminations. This model emphasizes the critical role of the significant energy absorbed by individual electrons from an EMP. It also shows the prominence of radiation, particularly within the electron density range of the antenna. Finally, this model offers valuable insights into the underlying physical mechanisms.
