Modeling and Measurement of Complex Permittivity of Soils in UHF
IEEE Geoscience and Remote Sensing Letters, 2020The complex permittivity of different types of soils in the ultrahigh frequency (UHF) is studied in this letter. A new model, whose inputs are the low-frequency conductivity and the volumetric water content, is proposed to estimate the complex permittivity of soils in UHF.

Simple Nondestructive Method for the Measurement of Complex Permittivity
IEEE Transactions on Instrumentation and Measurement, 1974A simple nondestructive method is presented for the measurement of the complex permittivity ?r of materials. The reflection coefficient ? of a flanged open-ended rectangular waveguide placed, next to a flat large sample is computed by a variational method as a function of the dielectric constant.

A spectrometer for the measurement of complex permittivity
Journal of Physics E: Scientific Instruments, 1972The spectrometer uses an unbalanced AC bridge and records the real or imaginary component of permittivity on a chart recorder over the frequency range from about 1 Hz to 1 MHz. The measured sensitivity extends to values of loss tangent of about 10-3 although the ultimate sensitivity is expected to be higher.

A modified calibration method for complex permittivity measurement
Review of Scientific Instruments, 2013This work proposes a calibration method to determine the complex permittivity of materials based on the cavity-perturbation method. The method can characterize a sample with relative large in volume or high in dielectric constant, which significantly broadens the scope of the conventional perturbation method.

Non-Destructive Measurement of Complex Permittivity for Dielectric Slabs
4th European Microwave Conference, 1974, 1974A method has been developed for a precise non-destructive measurement of the dielectric constant and losses of slab-like samples, such as microstrip substrates for instance. The test setup basically consists of an open-ended rectangular waveguide whose flange is placed in contact with one side of the dielectric material, the other one being backed by a

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 ...
