Nonstationary waveguide equations for investigation of ultrawideband pulses in irregular waveguides

Abstract

Nonstationary waveguide equations for investigation of the processes of excitation and propagation of ultrawideband pulses in irregular electromagnetic waveguides are derived. The equations allow direct calculation of the electric-field intensity of the pulses as a function of the spatial coordinates of the observation point and time. The intensity of the magnetic field is determined at the next stage after additional calculations. The equations proposed are a supplement to and a generalization of the equations derived earlier.
