Abstract
This paper presents an evaluation and tabulation, as a function of c/a and the normalized frequency θ2 = a2 σ μdcω, of the circular permeability μ = μ′ - j μ″ defined from its impedance at circular frequency ω and normalized to the dc circular permeability μdc. The results apply to a ferromagnetic cylinder of diameter 2a and conductivity σ with bamboo domains of sizes 2c.
