Carbon nanotubes (CNTs) have a unique ID tubular structure and high electronic conductivity, which are considered as typical dielectric loss material with high

complex permittivity [22-24].

These physical quantities are transformed in the

complex permittivity [epsilon]*[[omega]], complex conductivity [sigma]*[[omega]] = j[omega][epsilon]*[[omega]], complex resistivity [rho]*[[omega]] = 1/[sigma]*[[omega]], and complex electrical modulus M*[[omega]] = 1/[epsilon]*[[omega]] [4].

As shown by Kaler and Jones (20) at frequencies higher than 10 kHz the sinusoidal steady-state dielectric response of a spherical living cell can be represented by an equivalent homogeneous sphere of radius r + [delta] and the

complex permittivity [[epsilon].

The common approach is to approximate the relative

complex permittivity by means of rational or polynomial functions resulting in auxiliary differential equation FDTD models.

Complex permittivity can be measured using a number of techniques, including waveguide, cavity resonator, open resonant cavities, split-post dielectric resonator and free-space techniques.

Among specific topics are the

complex permittivity of soils in western Rajasthan at microwave frequency, Compton scattering and electronic properties of tungsten ditelluride, structural and electrical conductivity studies in nickel ferrite nanoparticles, and the temperature dependent elastic moduli of liquid potassium.

In order to destroy cancer cells by electromagnetic radiation, it is first necessary to determine the

complex permittivity of the cells.

However, instead of directly measuring the change in velocity and attenuation in this study, we measure a more fundamental quantity, the liquid's

complex permittivity, which we use as a basis for distinguishing one liquid from another.

A trend of the variation of the

complex permittivity as a function of the filling ratio of the metal is shown in Figure 13, utilizing the first order Effective Medium Theory formulas as in [29].

Thus, mixing formulas are developed to quantitatively predict the effective

complex permittivity of the composite materials by knowing the dielectric properties of its constituents.

Reliable and accurate determination technique of

complex permittivity of practical materials is a challenging problem [1].

The method is fast, accurate and convenient for measuring

complex permittivity and complex permeability of a material.
