Dipolar resonance in the plane-wave scattering by an axially magnetized ferrite cylinder

The scattering of E-polarized plane waves by an infinitely long axially magnetized ferrite cylinder is investigated for the case in which the radius of the cylinder is small in comparison with the wavelength of the incident wave. The scattering amplitude is found to have a maximum at a single resonant frequency whose approximate expression in terms of the physical parameters is deduced.
