“…Any single technique for complex permittivity measurement is not suitable over a wide range of frequency and complex permittivity. Numerous techniques for determination of dielectric properties of dielectric material have been developed [2][3]. In past various techniques in both the frequency and time domains have been used to measure the dielectric properties of materials at microwave frequencies [5][6][7][8][9].…”

Real and imaginary parts of complex permittivity of Aviation Turbine Kerosine (Hydro-fined) JetA-1 and Aviation Turbine Kerosine (Copper-Sweetened) JetA-1 are measured over the wide frequency range 8-12 GHz using X-band rectangular cavity resonator. The measurement technique uses the cavity perturbation technique. The fuel sample is filled in thin capillary tube of low loss material. It is then inserted through a sample hole at the centre of the broader side of the waveguide cavity resonator. The sample shifts the resonance frequency. The resonance frequency and shift in resonance frequency are measured using PNA Network Analyzer (AT E8362C). Validity of present measurement technique has been checked by measuring the dielectric properties of well-known dielectric materials (Plexiglas). Due to lack of experimental data in literature on dielectric parameters of Aviation fuels, it would be of great interest for the community to find its dielectric properties over wider frequency range. In addition the estimation of measurement error associated with this technique is also discussed.

“…Adjustment for errors due to gaps around the sample is obtained from equations available in the literature [33,34,35]. The formulas given in the literature generally under-correct for the real part of the permittivity and over-correct for the imaginary part of the permittivity.…”

“…Various researchers have approached the gap problem by representing the sample with air gap as a layered capacitor [33,34,41]. This approach assumes that the gaps between transmission hne and sample are effectively modeled by a set of capacitors in series.…”

Abstract-This paper presents modeling of the complex permeability spectra, fabrication and a wide frequency range characterization of a toroidal LTCC ferrite sample. A commercial ferrite tape ESL 40012 is used, and standard LTCC (Low Temperature Co-fired Ceramic) processing has been applied to the sample fabrication. The characterization was performed using a short coaxial sample holder and a vector network analyzer in the frequency range from 300 kHz to 1 GHz, at different temperatures. Using the model of the complex permeability spectra dispersion parameters of ferrite LTCC material has been determined for various temperatures. Characteristics of test samples are compared with modeled results and commercially available toroid made of similar NiZn ferrite material.
