Abstract
To quantify the effect of air gap on the dielectric constant measurement of low-loss materials, this letter presents the first quantitative study of the effect of five different shapes on the dielectric constant measurement using three low-loss materials as examples. The experimental results show that if low-loss materials’ dielectric constant measurement error is controlled within 5%, the air gap cannot exceed 4%. The results of this letter can provide effective guidance and reference for improving the measurement accuracy of electromagnetic parameters of low-loss materials.
期刊介绍:
The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
