A mesh-free particle method is presented for electromagnetic (EM) transient simulation. The basic idea is to obtain numerical solutionsfor the partial differential equations describing the EM problem in time domain, by using a set of particles, considered as spatialinterpolation points of the field variables, arbitrarily placed in the problem domain and by avoiding the use of a regular mesh. Irregularproblem geometry with diffused nonhomogeneous media can be modeled only with an initial set of arbitrarily distributed particles.Consistency recovery strategy of the numerical scheme is discussed and enforced. The time dependence is accounted for with an explicitfinite-difference scheme. Comparison with analytical solution for a 2-D case study is shown.
