Non-destructive complex permittivity measurement of low permittivity thin film materials

Measurement Science and Technology, 2007
Complex permittivity measurement of low permittivity thin films is necessary to understand the fundamental properties and to implement these materials in devices. A new technique has been developed employing split-post dielectric resonators at operating frequencies of 10 GHz and 20 GHz to measure relative permittivity and loss tangent of low ...

Measurement of complex permittivity of liquids. II

Journal of Physics E: Scientific Instruments, 1974
Improvements on the method of Lovell and Cole (1959) for the measurement of complex permittivity of liquids by means of the Boonton R-X Meter are presented. A new approach to the calibration of the cell and connecting line, considering ohmic losses, is described.

Measurement of complex permittivity of liquid dielectrics

Microwave and Optical Technology Letters, 2002
AbstractThe 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.

Complex Permittivity Measurement Using the Annular Slot

2005 IEEE Antennas and Propagation Society International Symposium, 2005
A new technique using a multi-port annular slot antenna for the measurement of complex permittivity is developed. The benefit of this now technique is that a two port network can be used on a planar device. The forward case of measuring S/sub 21/ is combined with a simple but effective calibration technique to compensate for the feed network.

Complex Permittivity Measurement Based on Transmitted Power

2019 IEEE Indian Conference on Antennas and Propogation (InCAP), 2019
This paper presents a novel complex permittivity measurement using transmitted-power function enforced at multiple frequencies. The method can easily retrieve the dielectric constants of low-loss and lossy materials utilizing the transmitted power without the need for phase information.

Measurement of Complex Permittivity and Permeability

1970
Abstract : 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 ...

International Comparison of Complex Permittivity Measurement at 9 GHz

IEEE Transactions on Instrumentation and Measurement, 1974
Dielectric constant and loss measurements made by three government laboratories (of the USSR, Canada, and the U. S. A.) are compared. The two materials measured were glasses. The measurements utilized cavity resonators in the H01n mode. The errors in dielectric constant reported by the laboratories were usually ± 0.3 percent; actual differences between

Nondestructive measurement of complex permittivity of sheet material

Microwave and Optical Technology Letters, 2003
AbstractIn this paper, we present a new model to determine the dielectric constant and the loss tangent of dielectric material in the sheet/slab form, with both low and high relative permittivity. A non‐destructive testing method is used, based on the microstrip patch and line resonators.
