Feasible Extraction Method for Permittivity Determination of Reflection-Asymmetric Structures
A feasible, yet accurate, extraction method is proposed for permittivity determination of a low-loss material positioned on a substrate material using reference-plane-invariant (RPI) transmission/reflection measurements. The method, in addition to its RPI property, does not necessitate the thickness information of the sample and substrate material. Its working principle is based on isolation of first reflected peaks of forward and backward reflection scattering parameters through a proper time-gating procedure. Permittivity measurements have been performed for acrylonitrile butadiene styrene (ABS), polyethylene terephthalate glycol (PET-G), and the polylactic acid sample for validation of our method. The effects of number of frequency points and the value of bandwidth (BW) on permittivity measurements are examined.
期刊介绍：
The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society 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.
