Non-linear inversion for relative permittivity
, 2009 The gradient method, Levenberg-Marquardt (LM) method, L₂ cooled roughness (CRL2) method and L₁ cooled roughness (CRL1) method are applied to the problem of recovering the relative permittivity structure of a dielectric object. The CRL1 method is a novel technique for the recovery of the relative permittivity structure of a dielectric object introduced ...

Characterization of Sub-Resonant Dielectric Spheres by Millimeter-Wave Scattering Measurements [PDF]
SensorsWhen measuring the size or relative permittivity of a dielectric particle, usually one of the parameters needs to be known for determining the other one. Scattering measurement methods offer an alternative that allows for extracting both the size and the

Experimental study of relative permittivity of atmospheric ice
, 2013 Atmospheric icing on onshore and offshore structures is problematic, if we don’t detect and remove it. Despite of various ice detection techniques, capacitor based ice sensing technique is interesting one, as it is based on dielectric properties of material. This technique of measuring icing event is simple and cost- effective.
