Broadband coaxial cavity resonator for complex permittivity measurements of liquids
A novel cavity perturbation technique using coaxial cavity ruonators for the measurement of complex permittivity of liquids is presented. The method employs two types of resonators (Resonator I and Resonator ll). Resonator l operates in the fre quency range 600 MHZ-7 CH2 and resonator ll operates in the frequency range 4 Gliz-14 CH2. The introduction of the capillary tube filled wit? the sampl...
متن کاملMeasurement of Complex Permittivity of Large Concrete Samples with an Open-Ended Coaxial Line
A 70 mm-open-ended coaxial line probe was developed to perform measurements of the dielectric properties of large concrete samples. The complex permittivity was measured in the frequency range 50 MHz – 1.5 GHz during the hardening process of the concrete. As expected, strong dependence of water content was observed.
متن کاملOpen-ended coaxial-line permittivity measurements on pulverized materials
The open-ended, coaxial-line probe technique can be used to obtain estimates of the pennittivities of some solid dielectrics over broad ranges of frequency by measurements on powdered or pulverized samples, but certain limitations must be recognized. Such a probe was used with a network analyzer to estimate the permittivities of coal and limestone from reflection coefficients measured on pulver...
متن کاملBiological Applications of a Technique for Broadband Complex Permittivity Measurements
A broadband coax technique developed by us for the measurement of dielectric properties of biological substances upto at least 20 GHz, is discussed. For water-based materials such as blood or muscle substitute phantoms, a 0.047 inch size probe is essential to minimize errors due to radiation. The data indicate the importance of the dielectric volume of the constituents, and enable tailoring of ...
متن کاملExtracting the Broadband permittivity of Liquids from Transmission Line Measurements
We present a semi-analytical procedure to extract the permittivity of fluids from measurements in our microfluidicmicroelectronic platform. This platform consists of broadband coplanar waveguide transmission lines with integrated microfluidic channels for characterizing the dielectric properties of submicroliter fluid samples. On-wafer calibration techniques are used to obtain the S-parameters ...
