Abstract
En 中文
Determining the high-frequency conductivity of a material is one of the critical steps in material characterization. In this paper, we introduce a new technique for determining the conductivity which is based on shielding effectiveness measurement in a rectangular waveguide. The proposed method has been validated using the simulation and measurement. The proposed method has shown a very good accuracy for determining the conductivity and has significant advantages over traditional techniques, such as simple setup/postprocessing, no need for vector measurement, high repeatability, and being capable of measuring high conductivities precisely. Besides these advantages, the proposed method has some limitation such as being suitable for good and/or thick conductors.
