Microwave transducers gained a wide distribution at realization of non-destructive materials control, both during manufacture, and at output trials stage. The analytical measuring instruments based on their application allow to define a wide spectrum of parameters of dielectric materials. When designing such devices the essential difficulties arise during carrying out precomputations. At this stage, it is necessary to obtain transformation functions between required parameters of checked objects and transducer output parameters. For this purpose, it is necessary to find a rigorous solution of an electromagnetic problem, having rather intricate boundary conditions, as a rule. Therefore, the developers usually refuse from a solution of an inverse problem allowing to find an optimum transducer's construction, and use the multiple approach to a direct problem with different input conditions. Creation of convenient for use calculation algorithms of microwave transducers allows to essentially reduce period of designing.

In this report the numerical algorithm and the calculation program of a capacity cavity microwave transducers with a small aperture is presented.
