Abstract

A device based on a split strip line (SSL) has been developed and experimentally investigated as DUT for research the backscattering matrix on a specialized installation. According to the requirements, the device contains two sections of the SSL, open for external electromagnetic influences, and a section with a ferrite bias substrate, which is magnetized in the longitudinal direction by applying a current to the solenoid. A combination of a priori reciprocal elements in the form of open SSL sections and a nonreciprocal element closed from the influence of electromagnetic waves has been obtained. The scattering parameters of the device are investigated in the frequency range up to 8 GHz. The dependence of the coefficients of the scattering matrix on the frequency and magnetized current in the solenoid enclosing the ferrite substrate is established. Sub-bands of frequencies and modes of use are indicated in which nonreciprocal properties are expressed to a certain extent.

基于铁氧体衬底的分带线非互易可控器件的实验研究

本文研制了一种基于分离带线(SSL)的测试装置，并对其进行了实验研究，用于在专用装置上研究后向散射矩阵。根据要求，该装置包含两段SSL，一段为外部电磁影响开放，另一段带有铁氧体偏置衬底，通过向螺线管施加电流在纵向上磁化。得到了开放SSL截面形式的先验互反元素和不受电磁波影响的非互反元素的组合。研究了该器件在8ghz频率范围内的散射参数。建立了散射矩阵的系数与包围铁氧体衬底的螺线管内的频率和磁化电流的关系。指出了频率和使用方式的子带，其中非互反性质在一定程度上得到了表达。
