GB/T 42741-2023
Introduction
GB/T 42741-2023 Solid Material Electromagnetic Parameter Measurement Method Using Free Space Technique is a national standard of China that provides guidelines for measuring the electromagnetic parameters of solid materials using the free space technique.
This standard aims to ensure accurate and reliable measurement of electromagnetic parameters such as permittivity, permeability, and complex impedance of solid materials. The free space technique involves measuring the reflection and transmission coefficients of electromagnetic waves in a free space environment, which eliminates the need for physical contact with the material being measured.
The standard outlines the measurement procedures, equipment requirements, and data analysis methods for conducting electromagnetic parameter measurements using the free space technique. It provides detailed instructions on calibrating the measurement system, setting up the measurement environment, and accurately positioning the material sample.
By following this standard, researchers and engineers can obtain precise measurements of electromagnetic parameters, which are crucial for the design and optimization of electronic devices and systems. It also facilitates the comparison and exchange of measurement data between different laboratories and industries.
Overall, GB/T 42741-2023 is an essential standard for anyone involved in the measurement and characterization of solid materials' electromagnetic parameters using the free space technique.
