Abstract

The method for Lyapunov exponents spectrum calculation for distributed infinite-dimensional beam-plasma systems in the framework of PIC-method was developed. Suggested approach was successfully approved by diagnosing oscillation dynamic modes of Pierce diode, an etalon model of microwave electronics. We discussed electron flow behavior in an autonomous Pierce diode in presence of ionic background in the interaction space. The possibility of system dynamics analysis in a wide range of controlling parameters was shown.
