The dielectric properties and tunability of multilayer thin films with compositional PbZr0.52Ti0.48O3/Bi1.5Zn1.0Nb1.5O7 (PZT/BZN) layers (PPBLs) fabricated by pulsed laser deposition on Pt/TiO2/SiO2/Si substrate have been investigated. Dielectric measurements indicate that the PZT/BZN bilayer thin films exhibit medium dielectric constant of about 490, low loss tangent of 0.017, and superior tun...

Bentonite-derived monolithic materials with and without distributed nanoscale turbostratic carbon, obtained by hot-pressing organobentonite and bentonite particles, respectively, in the absence of an added binder, exhibit exceptionally high dielectric loss while the electrical conductivity is relatively low. The combination of high dielectric loss and relatively low conductivity has not been pr...

The article focuses on the measurement and calculation of dielectric properties of biological tissue in the frequency band 4,5 GHz – 16 GHz. Special attention is paid to the frequency and thermal dependence dielectric constant and loss factor. Observed frequency changes of biological tissue dielectric properties obey causality, i.e. Kramers-Krönig relationships which relate changes of dielectri...

The frequency dependent dielectric properties of Ni1−xCdxCrxFe2−xO4 (x = 0.0, 0.3, 0.5, 0.7 and 1.0) spinel ferrite system are studied by measuring dielectric constant (ε′), dielectric loss (D) and conductivity (σa.c) at 300 K in the frequency range 100 Hz-2 MHz. The highest value of σa.c and ε′ is observed for x = 0.3 composition. The values ε′ and σa.c decrease with increase in frequency for ...

A process for rapid sterilization and aseptic packaging of sweet potato puree using a continuous flow microwave system operating at 915 MHz has been successfully developed. In microwave processing, dielectric properties have a major role in determining the interaction between purees and the electromagnetic energy. The objective of this research was to determine how dielectric properties are aff...

An effective approach to characterize frequency-dispersive sheet materials over a wide RF and microwave frequency range based on planar transmission line geometries and a genetic algorithm is proposed. S-parameters of a planar transmission line structure with a sheet material under test as a substrate of this line are measured using a vector network analyzer (VNA). The measured S-parameters are...

La₁-xSrxTiO3+δ (LST) has been studied in many fields, especially in the field of microelectronics due to its excellent electrical performance. Our previous theoretical simulated work has suggested that LST has good dielectric properties, but there are rare reports about this, especially experimental reports. In this paper, LST was prepared using a solid-state reaction method. The X-rays diffrac...

The paper reports electrical properties of human blood and plasma of belonging to different physiological and environmental conditions. Dielectric parameters such as dielectric constant, dielectric loss and electrical conductivity of human blood and plasma of groups A, B, AB and O are measured at the frequency of 1kHz using digital LCZ meter. It is found that the values of dielectric constant, ...

Abstract. Relationships among average spectral re ectance measured in the visible and near infrared (VNIR) region (0.4–2.5mm), dielectric constantmeasured in the microwave region (0.5–18GHz) and chemical content of 34 sedimentary rock samples were measured. The natural logarithm of the average spectral re ectance and that of the imaginary part of the dielectric constantwere negatively correla...
