Characterization of Relative Complex Permittivity and Permeability for Magneto-Dielectric Sheets
IEEE Transactions on Electromagnetic Compatibility, 2018 A new method is developed to extract relative complex permittivity and permeability of magneto-dielectric sheets. Two test fixtures are used to separately extract electric and magnetic properties of the material under test (MUT). The unknown parameters corresponding to dispersion models of the complex permittivity and permeability of the magneto ...

Complex effective relative permittivity of soil samples from the taunus region (Germany)
Journal of Earth Science, 2010 The most important parameter affecting ground-penetrating radar (GPR) measurements is the complex effective relative permittivity ɛr,eff* because it controls the propagation velocity and the reflection of GPR pulses. Knowing ɛr,eff* of soils passed through by electromagnetic waves increases accuracy in soil thickness and interface identification ...

Physiological Measurement, 2019 Electrical conductivity and relative permittivity are properties that indicate muscle health and they have different values parallel and perpendicular to the direction of the myofiber, a concept known as anisotropy. When the intrinsic electrical properties of muscle have ratios of anisotropy that are different then there is no analytical solution that ...

Electronics and Communications in Japan (Part III: Fundamental Electronic Science), 1990 AbstractFrom the measurement of a reflected voltage waveform from a biological body for a step‐like voltage waveform, the frequency characteristics of the complex relative permittivity are studied and the following results are obtained: (1) if the blood flow and sweating are normal, the value of tanδ in the mouth is 4 ‐ 6 at about 10 MHz because ...

IEEE Transactions on Terahertz Science and Technology, 2014 For measuring complex relative permittivity of more than 300 GHz in the THz region, time-domain spectroscopy (TDS) is usually used. On the other hand, a free-space method using a vector network analyzer (VNA) is used below 300 GHz. However, these methods have not been compared and continuity of complex relative permittivity measurement around 300 GHz ...

Relative complex permittivity and its dependence on frequency
World Journal of Engineering, 2017Purpose This paper aims to give a brief overview of dielectric properties, relative complex permittivity and its dependence on frequency. The significance of different approaches to complex permittivity is also discussed. Design/methodology/approach The different mechanisms of polarization are then presented.
