N2 - Ferrite filled coaxial lines have been shown to sharpen input pulses due to their nonlinear magnetic properties. This effect can be amplified by applying an axial magnetic biasing field. In addition to a steeper leading edge, oscillations in the microwave bands have been observed. These oscillations arise from damped gyromagnetic precession occurring in the ferrite. The magnetic bias necessary to generate damped oscillations and steepened pulse sharpening effects is produced by two separate means; a current carrying solenoid or, the less investigated case, permanent magnets. Multiple NLTLs are tested at lengths of 0.3 meters and 1 meter with an outer diameter of 13 mm. Permanent magnets with varying strengths were placed in different locations for multiple tests. Experiments and setups for these designs are detailed and their results are discussed.
