complex permittivity

Better performance can be achieved if more complex permittivity data are available for the training of the networks.

Commercial bridges for measuring complex permittivity were not available.

Improved complex permittivity measurement and data processing technique for soil-water systems.

Both the change in velocity and the energy loss depend on the complex permittivity of the cometary materials.

The complex permittivity at high frequencies was measured for three different shales:

A more extended version was given in Complex Permittivity published in 1971.

Complex permittivity and permeability are derived from metamaterials using the effective medium approach.

At the high-frequency limit, the complex permittivity is commonly referred to as ε.

It should be emphasized that the characteristic frequency is not the same when the analysis is carried out in terms of the complex permittivity.

In this formalism, the complex permittivity is defined as:

Complex permittivity measurement system for detecting soil contamination.

Effect of permeating solutions on complex permittivity of compacted clay.

This quantity, hereafter referred to as the materials' "dielectric function," is complex permittivity.

The anisotropy in complex permittivity is a potential parameter in shale characterization.

This study describes a new approach to analyze complex permittivity data of shales and to extract fundamental properties relevant to engineering applications.

Key words: heavy metals, subsurface contamination, complex permittivity, artificial neural networks, contaminant detection.

The complex permittivity changed with the advance of the concentration front, reflecting the decrease in moisture content and the increase in conductivity.

"Complex permittivity measurement ofliquids with coaxial cavity resonators using perturbation technique".

Key words: complex permittivity, nondestructive testing, soil contamination, detection of soil contamination, environmental technology.

Once the complex permittivity of the material is known, we can easily calculate its effective conductivity and dielectric loss tangent as:

In addition, where is the complex permeability and is the complex permittivity of the medium into which one is radiating.

The use of the complex permittivity, an intrinsic electrical property of materials, to detect the presence and type of heavy metals in soil is investigated.
