The magnitude of the electrical and mechanical losses of devices made from ferroelectric ceramics, which are currently widely used in electronic circuits, often determines the applications of these materials. In this article the current understanding of the mechanisms and their dependence on the ...
In the application of tuneable microwave devices of ferroelectric (BaSr)TiO3 systems the two critical parameters needed for optimal device performance are high tunability and low dielectric loss. The dielectric loss of the materials is strongly dependent on microstructure. This paper is concerned with ...

The introduction of an additional dielectric layer with a low permittivity between the ferroelectric layer and a metal shell makes possible a decrease in the waveguide energy losses, while retaining the desired control over the spectrum. The results of calculations of the Q value and the group ...
The performance of a ferroelectric Ericsson refrigeration cycle is investigated on the basis of the statistic relation between the electrical polarization and the electric field strength of the ferroelectric materials. The inherent regenerative losses in the cycle are calculated. The coefficients of performa...

A simple method of calculating the energy losses resulting from Vavilov- Cherenkov radiation in a transparent uniaxial ferroelectric is proposed. Formulas are obtained that permit a determination of the losses by a point charge and an analysis of the conditions necessary for the production of this ra...

Photovoltaic solar cells based on metal-halide perovskites have gained considerable attention over the past decade because of their potentially low production cost, earth-abundant raw materials, ease of fabrication and ever-increasing power-conversion ef
