高温度超导在微波中的应用取得了初步成功，导致了在液氮温度下工作的微波电子学的新分支的创建。在这方面，我们应该重新考虑非线性介电体在微波中的行为。讨论了YBa2Cu9O7−x/(BaxSr1−x)TiO9/YBa2Cu9O7−x三层结构电容器的特性。假设氧化学计量学对结构性质的重要影响。包含非线性介质的层状结构可作为微波电路参数电压控制器件的基础。
Abstract The initial success in high-T c superconductivity applications at microwaves leads to the creation of new branch in microwave electronics operating at liquid nitrogen temperature. In this connection one should reconsider the behaviour of nonlinear dielectrics at microwaves. The characteristics of a capacitor in the form of trilayer structure YBa2Cu9O7−x/(BaxSr1−x)TiO9/YBa2Cu9O7−x are discussed. The crucial influence of oxygen stoichiometry on the structure properties is assumed. The layered structures including non-linear dielectrics could be used as a basis for devices with voltage control of the microwave circuit parameters.
