Nonlinear Electromagnetic Scattering from a Diode Circuit

Electromagnetic scattering from an active diode circuit is considered. The focus is on the nonlinear interaction between the incident fields and the internal circuit sources. This interaction results in a mixing of frequencies between the incident and internal sources. An equivalent circuit model of the diode circuit and dipole antenna is presented and a nonlinear differential equation derived. This equation is solved approximately by a Volterra series to third order. This solution is simulated and numerical values of total scattered power at the various frequencies are calculated. Keywords include Electromagnetic scattering Nonlinear scattering Volterra series and Diode circuit.
