Rework Example 9.4 with a slab spacing of s = 2 mm and a remanent magnetization of 1000 G. (Assume all other parameters as unchanged and that the differential phase shift is linearly proportional to κ.)
Example 9.4 A thin ferrite rod with 4π Ms = 800 G is magnetically biased along its axis. Find the external bias field strength required to produce a gyromagnetic resonance at 2.52 GHz.
