适用范围：This International Standard describes methods of measuring the properties used to specifypolycrystalline microwave ferrites in accordance with IEC 60392 and for general use in ferritetechnology. 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, butalso materials with garnet and hexagonal structures;– the “microwave” region is taken to include wavelengths approximately between 1 m and 1 mm, the main interestbeing 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 maybe used in reciprocal devices as well, for example, modulators and (reciprocal) phase-shifters. Other applicationsinclude gyromagnetic filters, limiters and more sophisticated devices, such as parametric amplifiers.
