Measurement of Complex Permeability of Thick Film Materials in the 0.1 GHz~0.6GHz Band

Abstract:

The existing low-frequency magnetic parameter test is mainly based on impedance analysis,Its sample needs to be prepared into a ring,the hard materials are difficult to process into rings for testing. Small piece of material cannot be tested using impedance analysis because it is too small to be cut into a ring for testing. In this paper, the principle of impedance analysis and the basic theory of strip line be used, an empirical formula for the complex permeability of the magnetic bulk thick film material in the 0.1Ghz~0.6GHz frequency band is obtained through design and test by design simulation and physical fixture, it makes the testing of the complex permeability of thick film materials easier due to it avoid damage and ring cutting before testing.
