Introduction - Broadband Reflectometry for Enhanced Diagnostics and Monitoring Applications - page 7

Successively, a method that takes into account the frequency-dependence of the
dielectric permittivity of the moistened granular material (considering the permit-
tivity of each single constituent) is presented. This application is also used as a
test-case for validating an innovative calibration procedure that becomes especially
useful when the traditional SOL calibration cannot be performed. Furthermore, the
adoption of antennas in place of the traditional probes is discussed, thus assessing
the possibility of achieving a noninvasive approach.
At the end of chapter fifth, two innovative strategies for enhancing and simpli-
fying TDR-based measurements of electrical conductivity (typically used in soil
science) are also addressed.
Finally, the sixth chapter provides some significant examples on the use of
TD/FD combined approach for the characterization of antennas. In particular, some
guidelines are given for obtaining accurate results even without resorting to expen-
sive facilities such as anechoic chambers. The presented procedure can be extended
to other electronic devices or systems as well.
