The following information applies to Questions 6 – 9. Consider a two-slab remanent (latching) phase shifter realized in standard X-band waveguide (WR-90) and operating at 9 GHz with lossless ferrite having 4πMr = 1500 G and εr = 13. Assume that the slab thickness is 2 mm and the slabs are placed symmetrically about the center line, each 9 mm from one of the narrow walls of the waveguide. (You can refer to Figure 9.10 for the geometry.) Use of the MATLAB routines provided to you is highly recommended. What is the value of the permeability tensor element μ for the ferrite material relative to the permeability of free space? Type your answer as a dimensionless quantity to three places after the decimal.

Consider the case where an infinite ferrite region is biased such that the direction of propagation is perpendicular to the direction of the magnetic bias. In this case, the two eigenmodes are called “ordinary wave” and “extraordinary wave”. Which equation below gives the correct one for calculating the effective permeability for the extraordinary wave in terms of the permeability tensor elements
