Medium Frequency broadcasting is still a powerful tool for information transmission. But, on the other hand, high power radio waves cause errors in the normal operation of electronic devices inside buildings. So the knowledge of the shielding effect by the building and the distribution of electromagnetic field strength within it are necessary. The numerical simulation of electric field distribution inside of building structures in such environment gives a useful information at building designs. The paper describes the simulation results of this problem by using the finite differential time domain method. The results are confirmed by experiments using scale models.
