Abstract : A fin-line waveguide device for modulating signals passing therethrough. The device comprises a fin-line waveguide including two channel members longitudinally extending in the direction of signal propagation through the device. The channel members are physically and electrically separated by a ferrite dielectric slab which is oriented in a longitudinally extending plane parallel to the electric field lines of the signal passing through the device. A magnetic field is applied to the ferrite slab to magnetically bias the slab to ferromagnetic resonance. A voltage is applied across the ferrite slab to alter the ferromagnetic resonance characteristics of the slab. The phase and amplitude of the signal processing through the waveguide are modulated in response to the applied voltage.
