Permittivity measurement of cementitious materials with an open-ended coaxial probe
Construction and Building Materials, 2020 Abstract This study presents a methodology to investigate the complex permittivity of heterogeneous samples like concrete, mortars and cement pastes by using an open-ended coaxial probe. The probe is associated with portable Vector Network Analyser (VNA) allowing in-situ measurements.

Evaluation of Apple Maturity with Two Types of Dielectric Probes
Sensors, 2018 The observed dielectric spectrum of ripe apples in the last period of shelf-life was analyzed using a multipole dielectric relaxation model, which assumes three active relaxation processes: primary α-process (water relaxation) and two secondary processes
