1   Scope This International Standard describes methods of measuring the properties used to specify polycrystalline microwave ferrites in accordance with IEC 60392 and for general use in ferrite technology. These measuring methods are intended for the investigation of materials, generally referred to as ferrites, for application at microwave frequencies. Single crystals and thin films generally fall outside the scope of this standard. NOTE 1 For the purposes of this standard, the words “ferrite” and “microwave” are used in a broad sense: – by “ferrites” is meant not only magneto-dielectric chemical components having a spinel crystal structure, but also materials with garnet and hexagonal structures; – the “microwave” region is taken to include wavelengths approximately between 1 m and 1 mm, the main interest being concentrated on the region 0,3 m to 10 mm. NOTE 2 Examples of components employing microwave ferrites are non-reciprocal devices such as circulators, isolators and non-reciprocal phase-shifters. These constitute the major field of application, but the materials may be used in reciprocal devices as well, for example, modulators and (reciprocal) phase-shifters. Other applications include gyromagnetic filters, limiters and...

:Sm1.5Y0.5Fe17-xSix及其复合材料可调内禀磁性和微波吸收性能

作者通过改变Sm1.5Y0.5Fe17化合物固有磁性,证明Si对微波吸收频率和电磁匹配具有显著调谐作用。微波测量结果显示了固有磁性与微波吸收特性之间内在联系:随着Si含量增加,具有相同复合厚度反射损耗(RL)峰值峰值频率(fp)有增加。此外,在复合材料中还发现了非常高介电微波吸收峰,这可以在一定程度上进一步提高有效吸收带宽(QB)。...

十五种液位计动图演示、应用、参数,你都知道么?

它是通过一个可以发射能量波(一般为脉冲信号)装置发射能量波,能量波遇到障碍物反射,由一个接收装置接收反射信号。根据测量能量波运动过程时间差来确定物位变化情况。由电子装置对微波信号进行处理,最终转化成与物位相关电信号。在微波物位测量设备中,使用能量波通常是频率为8.3GHz(大多在6GHz左右,也有更高频率高频电磁波。该设备使用能量波是脉冲能量波。...

“去伪存真”,锁相放大器在量子精密测量系统中应用

我们将微波频率定于NV色心连续波谱斜率最大处,则当外磁场发生变化,其荧光强度变化最明显,从而提高测量灵敏度。NV色心ODMR谱为了提高测量信号信噪比,通常采用锁相放大方法,将微波信号进行频率调制,从而避开电测量系统1/f噪声,实现更高测量精度。...
