Coupled lines printed on a ferrite substrate having the material properties 4πM_s = 1000 G, loss linewidth ΔH = 10 Oe, relative permittivity ε_r = 14 and dielectric loss tangent tanδ_ε = 0.0002. The internal DC magnetic field, H_i is assumed to be in z direction, normal to ground plane. Unit-cell dimensions are: l₁ = 120, l₂ = 200, w₁ = 60, w₂ = 20, w₃ = 30, s₁ = 105, s₂ = 10 (mils).
