Automatic measurement of complex dielectric constant and permeability at microwave frequencies |
| |
Abstract: | With the advent of the computer and automatic test equipment, new techniques for measuring complex dielectric constant (ε) and permeability (µ) can be considered. Such a technique is described where a system is employed that automatically measures the complex reflection and transmission coefficients that result when a sample of material is inserted in waveguide or a TEM transmission line. Measurement results of ε and µ for two common materials are presented. |
