TTwo types of tapered anechoic chambers have been analyzed by the method of mathematical modeling: conical and pyramidal types. The radar-absorbing coating of the inner surface of both chambers is modeled by a dielectric layer. The electromagnetic field inside the tapered chambers has been calculated by the method of integral equations using the FEKO software. The analysis and comparison of the electromagnetic field distribution in the quiet zone of each chamber have been carried out and the influence of the radiation source position on the distribution of the amplitude and phase of the field has been investigated at different frequencies.
