The d.c conductivity, static dielectric constant and thermopower of TTF—TCNQ have been calculated for temperatures below 54K within a self-consistent effective medium approximation. TTF—TCNQ is assumed to consist of small regions which are semiconducting and others which are highly conducting. The conducting regions have a large negative dielectric constant, a large d.c. conductivity and a nega...

Homogenization theory is used to calculate the macroscopic dielectric constant from the quantum microscopic dielectric function in a periodic medium. The method can be used to calculate any macroscopic constitutive relation, but it is illustrated here for the case of electrodynamics of matter. The so-called cell problem of homogenization theory is solved and an explicit expression is given for ...

A study was made on the effect of glycine on systems involving trypsin and BAEE(1) or TSAME on the one hand, or alpha-chymotrypsin with any of the substrates BAEE, TEE, or PEE, on the other. In all cases there was a linear relationship between the rate logarithm and the reciprocal of the dielectric constant of the glycine solution. The slopes were positive in the reactions of trypsin. In those ...

ABSTRACT. A new technique for the measurement of dielectric constant of materials, using a partially filled waveguide cell and a new mixture equation, has been developed which is first tested for teflon and then used to measure the dielectric constant of rice and air mixture in the frequency range of 2.6GHz to 3.9GHz. The values of dielectric constant of rice grain obtained using the mixture mo...

The dielectric properties, consisting of the dielectric constant (epsilon') and loss factor (epsilon''), were measured with an open-ended coaxial-line probe and impedance analyzer for uncooked broiler breast muscle pectoralis major and pectoralis minor, deboned at 2- and 24-h postmortem, over the frequency range from 10 to 1,800 MHz at temperatures ranging from 5 to 85 degrees C. The dielectric...
