Abstract: Microwave devices are widely used in the industry and in the specialized labo-ratory analyses. Development of such devices requires the possibility of modeling of microwave energy distribution in the specific resonant chambers. Until now, such mo-deling was possible only with the use of commercial software or was limited to specific cases. The paper presents an open-source module for ELMER software for solving time-harmonic Maxwell’s equations, allowing modeling of microwave waveguide lines. Three test cases of different resonant chambers are investigated at 2.45 GHz frequency. Model-ing results obtained from the open-source ELMER Vectorial Helmholtz module show that the application of this software can be effective in R&D works, enabling high-tech small and medium enterprises involvement in advanced microwave technology.
