摘要：
Microwave slot and coplanar transmission lines formed on a surface of ferroelectric films grown on dielectric substrates are used for various microwave devices with electrically tunable amplitude and phase frequency characteristics. The electric field intensity, which is required for the effective modulation of dielectric permittivity of the ferroelectric film is varied between 10 and 15 V/micron. Therefore rather narrow gaps with width no more than 10 microns can provide necessary electric field at bias voltage no more than 100 V. In this case the attenuation of the electromagnetic slot mode is considerably increased, so the implementation of such devices has no a sense.
