【 摘 要 】

In this paper, the results of an investigation of the resonance regime of shielding of cylindrical conducting enclosure as unmanned aerial vehicle hull model with an inner filling of common constructive components are presented. Calculations of the hull shielding effectiveness so as the induced currents in the inner placed transmission line were done in FEKO on the basis of the confirmed accuracy of the simulation. It was found that the increasing the level of the hull inner filling would result in a shift of the shielding effectiveness resonances to lower frequencies. The difference between the shielding effectiveness of the hollow hull and 90%-filled can be of 50-100 dB.
