In this paper, electromagnetic wave analysis was performed efficiently in a large structure using the theoretical method. While taking into consideration the important assumptions of the employed theoretical method, we created an environment for measurement and simulation. A shield room with an aperture was selected as the target structure, and a measurement system based on frequency domain was constructed and used. Using the simulation tool, Wireless Insite, electromagnetic wave analysis was performed by modeling the measurement environment. To verify the efficiency and accuracy of the theoretical method, the results of the actual measurement, the commercially available simulation tool, and the theoretical method were compared. These results showed that the theoretical method can be more efficiently interpreted than the commercially available simulation tool in an electrically large structure.
