| Abstract: | A perturbation test method of rectangular cavity is discussed for determination of complex permittivity of dielectric materials at microwave frequencies. The electromagnetic field in the TE 10 n mode rectangular cavity is analysed in terms of theory after a dielectric sample is inserted in it. The corrected and accurate calculation formulas, which are similar to perturbation ones, are obtained by finding numerical solution of the field in the cavity. |
