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.-k e.- , .
