| Abstract: | Based on the perturbation theory, an automatic measurement system of virtual instrumentation by advanced vector network analyzer was developed for measuring electromagnetic parameters of nano-magnetic thin films materials under microwave frequency. By means of this system, the complex permittivity of thin films samples and its complex permeability can be measured quickly and accurately. LabVIEW, a kind of graphic programming language can reduce development time and improve programming efficiency. |
