Dielectric characterization of vegetation at L band using an open-ended coaxial probe [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2018 Decoupling the integrated microwave signal originating from soil and vegetation remains a challenge for all microwave remote sensing applications. To improve satellite and airborne microwave data products in forest environments, a precise and reliable

A Numerical Investigation of the Dispersion Law of Materials by Means of Multi-Length TDR Data
Remote Sensing, 2022 In this paper, we propose a method for retrieving the dispersion law of a material under test from multi-length TDR measurements in reflection mode, repeated at several frequencies.

Strain Sensor from Tapered Fibres [PDF]
EPJ Web of Conferences, 2020 A new all fibre, and low transmission loss, digital optical strain sensor is proposed. This sensor behaves as a Coaxial Mach-Zehnder interferometer. Special depressed cladding single-mode fibre DCF was tapered down to the micrometer scale presenting FSR ...

Coaxial probe in circular cylindrical cavity
Electronics Letters, 2006 Scattering from a conducting circular cylindrical cavity fed by a coaxial probe is studied. A fast convergent series solution is obtained by utilising the results of monopole radiation in parallel plates. Numerical results agree well with other existing results.

Coaxial atomic force microscope probes for imaging with dielectrophoresis [PDF]
Applied Physics Letters, 2011 We demonstrate atomic force microscope (AFM) imaging using dielectrophoresis (DEP) with coaxial probes. DEP provides force contrast allowing coaxial probes to image with enhanced spatial resolution. We model a coaxial probe as an electric dipole to provide analytic formulas for DEP between a dipole, dielectric spheres, and a dielectric substrate.

A High-Resolution Leaky Coaxial Cable Sensor Using a Wideband Chaotic Signal
Sensors, 2018 A high-resolution leaky coaxial cable (LCX) sensor for perimeter intrusion detection is proposed and experimentally demonstrated. In our proposed sensor system, a wideband Boolean-chaos signal is used as the probe signal, and a pair of leaky coaxial ...
