Title:
強誘電性デバイスおよびそれに関する方法
Document Type and Number:
Japanese Patent JP4307084
Kind Code:
B2
Abstract:
The present invention relates to an electrically controllable/tunable microwave device comprising a ferroelectric substrate with a variable dielectric permitivity and conducting electrodes, arranged on said substrate, and the capacitance of which depends on applied voltage C(V), the microwave device comprises at least two sections or parts of the substrate/electrodes for each of which different electrical field strengths are generated upon voltage application. Said generated electrical field strengths are controlled by means of the design of the device and/or the voltage application such that the slope (dC/dV) of the voltage dependence of the capacitance C(V) of the microwave device can be controlled.
