An overview of the state of art in ferroelectric thin films is presented. First, we review
applications: microsystems' applications, applications in high frequency electronics, and …

Reconfigurable antennas change polarization, operating frequency, or far-field pattern in
order to cope with changing system parameters. This paper reviews some of the past and …

Radar-absorbing materials are used in stealth technologies for concealment of an object
from radar detection. Resistive and/or magnetic composite materials are used to reduce the …

A review of the properties of ferroelectric materials that are relevant to microwave tunable
devices is presented: we discuss the theory of dielectric response of tunable bulk materials …

Electrically tunable dielectric materials have potential applications as various microwave
devices, such as tunable oscillators, phase shifters and varactors. High dielectric tunability …

Microwave devices based on tunable materials are of vigorous current interest. Typical
applications include phase shifters, antenna beam steering, filters, voltage controlled …

Thorough Raman and infrared (IR) reflectivity investigations of nominally pure SrTiO 3
ceramics in the 10–300 K range have revealed a clear presence of the polar phase whose …

Recent progress in the development of barium strontium titanate thin film varactors for room
temperature tunable microwave devices applications is reviewed, with emphasis on efforts …

Raman spectroscopy was used to demonstrate that the lattice dynamics of SrTiO3 (STO)
nanoparticles strongly depends on their microstructure, which is in turn determined by the …

The structure of the antiphase domain boundaries of strontium titanate SrTiO 3 that exist at
temperatures below the antiferrodistortive transition, is analyzed. It is found that some …
