Abstract
Nonlinear intermodulation coupling in ferrite junctions have been solved analytically for the first time. Primary microwave excitations of the ferrite junction at frequencies f1 and f2 will induce effective rf current at frequency 2f1-f2 which generate intermodulation field within the ferrite satisfying the boundary conditions at the junction boundary. The static demagnetizing field has been shown to have an adverse effect in increasing intermodulation coupling. Our calculations compare reasonably well with experiments.
