Permittivity of Porous Titanate Dielectrics [PDF]
Journal of the American Ceramic Society, 2006 Relative permittivities ranging from 12 to 100 were obtained from porous titania. Relative permittivities from 8 to 30 were obtained from porous calcium magnesium titanates. Porosity was introduced as microporosity by partial sintering, as 15 μm diameter spherical pores with porogens, and by fabrication of a microcellular structure

Dielectric permittivity estimation via TDR measurements
2009 International Conference on Electromagnetics in Advanced Applications, 2009 In this paper the determination of the permittivity of liquid or homogeneous dielectrics from their time-domain response is adressed. The analysis is based on a simplified model of the TDR measurement setup, where the probe is described by an ideal transmission line with a Debye permittivity. A simple formula to evaluate the permittivity is introduced,

Dielectric anisotropy in polar solvents under external fields [PDF]
, 2015 We investigate dielectric saturation and increment in polar liquids under external fields. We couple a previously introduced dipolar solvent model to a uniform electric field and derive the electrostatic kernel of interacting dipoles.
