Nonlinear extrinsic permittivity and piezoelectricity in lead titanate due to 90° domain walls pinning
It is known that the restoring force acting on a disequilibrated domain wall is the key factor, which controls macroscopic values of extrinsic (i.e. domain wall) contributions to permittivity and piezoelectricity. Considering the bu...

Dielectric Model of Polarization Mechanisms in Time Domain Field Simulation Including Temperature Dependence
The voltage distribution in an insulating system depends on the geometry and the permittivity of the applied dielectrics. The permittivity is frequency and temperature dependent. Understanding this dependence is important for the de...

Identification of microscopic domain wall motion from temperature dependence of nonlinear dielectric response.
It is known that the permittivity of ferroelectric polydomain films and single crystals in weak electric fields is strongly enhanced by the reversible movement measurement of a nonlinear macroscopic dielectric response. In addition,...

Relative Permittivity Measurement of 3D-textile
The paper deals with the relative permittivity determination of the 3D-textile by a transmission line method (TLM). Measuring points are shifted to avoid inaccuracies caused unknown permittivity. The relative permittivity o...
