Measurement of Complex Permittivity and Permeability
1970Abstract : The program was conducted to derive a better technique for the measurement of the permeability and permittivity of lossy ferrites at microwave frequencies at temperatures up to 1000F. Although the classical method of waveguide measurement techniques was used, a careful analysis of the sources of errors was undertaken and a computer aided ...

Measurement of complex permittivity of liquid dielectrics
Microwave and Optical Technology Letters, 2002AbstractThe complex permittivity of a number of liquid dielectrics has been measured with the use of the in‐waveguide technique at the X and Ku band. The TRL calibration procedure is applied for the calibration of the waveguide system. The measured results of permittivity of distilled water agree well with those published in the literature.

The Complex Permittivity of Polyethylene/Mica Composites
IEEE Transactions on Electrical Insulation, 1982The complex relative permittivity ?*(f) of polyethylene/mica composites has been measured in the frequency range 10-2 to 107 Hz, as a function of mica content ?2 and prior sample conditioning. ?*(f) was found to display two main features: ?'-?' ?and K'' vary as fn-1 with 0.64?n?0.83 for all ?2, on account of the intrinsic dispersive properties of the ...

Extended Mixing Rule to Complex Permittivity
Journal of the Korean Ceramic Society, 2003Various types of equation for mixing rule on permittivity of mixture have been proposed, but none of these is not perfect because of the inconsistency between the actual geometrical configuration and the basic model for calculation. Serial model and parallel model are lower and upper extremes of mixing manner, the apparent permittivity of any other ...

Complex Permittivity and Dipole Correlations
1974The relation of Glarum between macroscopic and microscopic relaxation functions has been derived by molecular response function theory, with effects of induced polarization included. A modified form of Zwanzig’s theory of rotational diffusion of interacting dipoles, based on Kirkwood’s theory of transport processes, is shown to give correlation ...

Complex Microwave Permittivity of Secondary High Explosives
Propellants, Explosives, Pyrotechnics, 2013AbstractWe aim to understand how microwaves interact with high explosives by studying the complex permittivity from 1–18 GHz of HMX, RDX, TNT, TATB, PETN, Octol, Comp B, 95 % RDX/5 % Viton A (PBX‐RDX), PBX 9404, PBXN‐5, PBXN‐7, PBXW‐14, PBX 9501, and PBX 9502.

Cryogenic complex anisotropic permittivity of magnesium fluoride
Materials Science and Engineering: A, 2006The complex tensor permittivity of MgF2 has been measured using whispering gallery mode and quasi TE0np dielectric post resonator techniques as a function of frequency and temperature. MgF2 exhibits uniaxial anisotropy. At room temperature permittivity component parallel to the anisotropy axis is 4.77 ± 0.2% and the component perpendicular to ...
