Theory of FTI Method for the Analysis of Electron and Ion Transport Properties

The theory of Right time integral (FTI) method deduced from the path-integral solution of the Boltzmann equation is described with procedures to obtain the velocity ditribution and transport properties of charged particles in gases under static external fields. Here, the normalized starting rate distribution Psi(Sn) (upsilon(0)), determined by iterative applications of loop dispersion function, is used as the principal unknown function. FTI method is essentially a trajectory analysis that reproduces the flight behavior of charged particles in gases and is stable as far as those have a steady state.
