Improved Permittivity Calibration Method for Wideband In Situ Permittivity Probe

IEEE Geoscience and Remote Sensing Letters, 2013
This letter discusses about an improved permittivity probe calibration method for calculating the complex permittivity of soils from reflection data over a very wide bandwidth. The accuracy of this method is demonstrated using reflection data collected from a unique wideband (10-1000 MHz) permittivity probe specifically designed for quick in situ ...

Optimization Techniques on Permittivity Distribution in Permittivity Graded Solid Insulators

Conference Record of the 2006 IEEE International Symposium on Electrical Insulation, 2006
We have proposed a new concept for solid insulation; an application of FGM (functionally graded materials). By controlling the distribution of dielectric permittivity inside solid insulators, we can achieve the efficient field control with keeping simple configuration of solid insulators.

Solid Mixture Permittivities

The Journal of Chemical Physics, 1955
A macroscopically homogeneous aggregate contains two materials A, B, with dielectric constants εA, εB, in volume ratio p: (1—p); what is the dielectric constant of the aggregate? By a method used by Yvon and others in molecular theory, this very old problem is formulated rigorously and solved in series form. One form of the solution is ε/ε′ = 1+⅓p(1—p)(

High permittivity dielectrics

2020
Abstract This chapter discusses high permittivity dielectrics such as hafnium oxide and zirconium oxide and how the phonons of such materials, their band and polarization behavior and silicon interact. High permittivity materials are used as dielectrics with semiconductors.

Microwave Permittivity Determination in Agricultural Products

Journal of Microwave Power and Electromagnetic Energy, 2002
Applications of microwave measurement techniques, including frequency-domain and time-domain methods, for determining the permittivity of agricultural products (seeds, plants, grains, fruits, meat, etc.) are reviewed. Graphical data illustrating the dependence of the dielectric constants and loss factors of such products on moisture content, frequency ...

Biomass measurement by inductive permittivity

Biotechnology and Bioengineering, 1997
An electrodeless, inductive permittivity probe is shown to reliably indicate fermentation biomass. By designing the probe based on electromagnetic induction, the electrode polarization artifact-common to electrode-based permittivity measurements of conductive solutions-is eliminated. The measurement of viable biomass concentration (X(V)) is precise and
