Abstract The electric field shielding effectiveness(SE) of the heterotypic enclosure with apertures is investigated by using the adjusted transmission line method(TLM). The electric shielding effectiveness is calculated as a function of the convexity structure height, span and the distance to the apertured face. It is shown as that the convexity structure deviates the resonance frequency of the cavity. When the interference signal frequency is greater than the resonance frequency of the cavity, the influence of convexity structure on shielding effectiveness will be enhanced as rising of the height, span and distance between the apertured face and the convexity structure. Results of adjusted TLM are in good agreement with the CST simulation results.
