High-frequency permeability of Ni and Co particle assemblies

High-frequency permeability of Ni and Co particle assemblies

A coaxial transmission line was constructed, characterized, and calibrated for the frequency dependent measurement of complex relative permeability (μr) and complex permittivity (εr). The permeability of Ni powder with a grain size of
