The influence of the dielectric constant in dielectric resonator antennas

2016 International Conference on Communications (COMM), 2016
This 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, 1951
A 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, 2012
Compound 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.

Dielectric constant

2004
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 =

Formulae for Dielectric Constant of Mixtures

Proceedings of the Physical Society. Section B, 1957
The major formulae suggested for the dielectric constant of a mixture of two components (at least one of which has the form of particles containing many molecules) are shown to be all related to another. The assumptions made in deriving the differing formulae are examined.
