Unique-Solution Single-Sample Complex Dielectric Characterization Through Linear Phase Approximation

open access: yesIEEE Open Journal of Antennas and Propagation, 2022
This paper presents a transmission-only (TO) approach that solves the long-standing problem of transmission phase ambiguity. The approach considers a linear frequency-dependent phase approximation to derive the phase mode value analytically and uniquely ...

Spectroscopic analysis and temperature-dependent dielectric properties of bulk Ni–Zn ceramics [PDF]

open access: yesJournal of Advanced Dielectrics, 2019
In the present work, series of Zn ion-doped Ni1−xZnxFe2O4 (0.0≤x≤0.5) ceramics were prepared by the double sintered solid-state reaction route to find out the influence of Zn2+ ions on the crystal structure, lattice structure and dielectric behavior of ...

Relative Permittivity Measurement of Microliter Volume Liquid Samples through Microwave Filters

open access: yesSensors, 2023
This paper proposes a concept of dielectric characterization of low-volume liquid samples using the coupling coefficient of filters. The concept is validated through a two-pole substrate integrated waveguide filter in which the liquid under test is ...

Evidence of a third kind of Johnscher’s like universal dielectric response [PDF]

open access: yesJournal of Advanced Dielectrics, 2018
Polymer/metal composites (PMC) comprising of polyvinylidene fluoride/nanocrystalline nickel with varying volume fractions of nickel (fcon) prepared under cold press show an insulator to metal transition (IMT) at percolation threshold (fc=fcon=0.27).

Application of Machine Learning to Predict Dielectric Properties of In Vivo Biological Tissue

open access: yesSensors, 2021
In this paper we revisited a database with measurements of the dielectric properties of rat muscles. Measurements were performed both in vivo and ex vivo; the latter were performed in tissues with varying levels of hydration.
