Analytical and Numerical Techniques for Analyzing an Electrically Short Dipole with a Nonlinear Load,

摘要

An electrically short dipole with a nonlinear dipole load is analyzed theoretically using both the analytical and numerical techniques. The analytical solution is given in terms of the Anger function of imaginary order and imaginary argument,and is derived from the nonlinear differential equation for the Thevenin's equivalent circuit of a dipole with a diode. The numerical technique used was to solve the nodal equation using a time-stepping finite difference equation method. The nonlinear resistance of the diode is treated using an iteration technique. A comparison between the analytical and numerical solutions is given.
