Изобретение относится к технике измерений с помощью СВЧ излучения и может использоваться в текстильной, бумажной и деревообрабатывающей промышленности. Для измерения свойств диэлектрического материала его размещают в объемном СВЧ резонаторе, в котором возбуждают две резонансные моды колебаний с взаимно ортогональной ориентацией их электрических полей. Исходную разность частот возбуждаемых мод выбирают из условия исключения возможности возникновения связи между ними. Измеряют функцию отношения и/или суммы сдвигов частот резонансных мод колебаний резонатора, обусловленных их взаимодействием с исследуемым материалом. По измеренной величине функции отношения сдвигов частот определяют степень анизотропии диэлектрической постоянной исследуемого материала, а по величине функции суммы сдвигов частот определяют его линейную плотность. Данный способ позволяет независимо с высокой точностью измерять указанные свойства анизотропных диэлектрических материалов.The invention relates to techniques for measuring using microwave radiation and can be used in the textile, paper and woodworking industries. To measure the properties of a dielectric material, it is placed in a volume microwave resonator, in which two resonant oscillation modes with mutually orthogonal orientation of their electric fields are excited. The initial frequency difference of the excited modes is chosen from the condition of exclusion of the possibility of a connection between them. Measure the ratio function and / or the sum of the frequency shifts of the resonant modes of the resonator oscillations due to their interaction with the material under study. The degree of anisotropy of the dielectric constant of the material under investigation is determined from the measured value of the ratio of frequency shifts, and its linear density is determined from the value of the sum of frequency shifts function. This method allows independently with high accuracy to measure the specified properties of anisotropic dielectric materials.
