The influence of the dielectric constant in dielectric resonator antennas
2016 International Conference on Communications (COMM), 2016This paper presents a comparison between dielectric resonator antennas with different dielectric constant parameter of the resonator. The antenna is fed with microstrip line. The dielectric resonators have cylindrical geometry. In HFSS software program, the simulations are up to compare the antennas' behavior as a function of different parameters, such

THE DIELECTRIC CONSTANT OF DISULPHUR DECAFLUORIDE
Canadian Journal of Chemistry, 1951A method is described for obtaining the dielectric constant and conductivity of disulphur decafluoride in both liquid and gaseous forms. The freezing point of the liquid and the molecular weight of the vapor are established as criteria of purity. All the measurements lead to the conclusion that disulphur decafluoride is non-polar.

Phthalocyanine with a giant dielectric constant
Dalton Transactions, 2012Compound 1 has been prepared by the reaction of 4-nitrophthalonitrile and trans-2-methoxy-4-(2-nitrovinil)phenol by the common method of nucleophilic substitution of an activated nitro group in an aromatic ring. The metallophthalocyanines 2, 3 were prepared by the reaction of a dinitrile derivative with Co(OAc)(2) or Zn(OAc)(2) in DMSO.

The dielectric constant K is a measure of a material’s ability to store electric charge. In scalar form the defining relations are as follows: . . . D = εE, . . . where D is the electric displacement measured in C/m2, ε is the electric permittivity in F/m, and E is electric field in V/m. The dielectric constant K is the relative permittivity: . . . K =

Field Dependence of the Dielectric Constant
Proceedings of the Physical Society. Section A, 1951A very general calculation has been made by Frohlich giving the dielectric constant of a material in terms of the spontaneous fluctuations of the electric moment of the material which would occur in a field-free region. This calculation is now extended one step further so as to include the first term in the field dependence of the dielectric constant ...

The Čerenkov Effect and the Dielectric Constant
Physical Review, 1953A quantum-mechanical theory of the \ifmmode \check{C}\else \v{C}\fi{}erenkov radiation is developed wherein the refractive medium is treated not as a continuum but as an aggregation of atoms. The atoms and the electromagnetic field are considered as forming a single system which interacts with an incident charged particle.

Dielectric constants of homogeneous mixture
Molecular Physics, 1965A new simple formula for the dielectric constants of homogeneous mixtures is derived. This formula contains expression (e1/3-1) instead of the usual quantity (e-1)/(e+2) (Clausius-Mosotti, Debye). Similarly, function (n 2/3-1) replaces (n 2-1)/(n 2+2) in the Lorentz-Lorenz formula.
