In this paper we analyze the shielding effectiveness of a thin-film screen in the time domain (TD). The excitation pulse is optimized with respect to various definitions of the TD shielding effectiveness (SE) concerning the peak value, the maximal derivative and the absorbed energy of the incident and shielded signals. A general approach to set parameters of the power exponential pulse as a key component of the test (namely the rise time, the rising power and the ringing frequency) with respect to different requirements on the device under test is proposed here. Two sample problems are solved using a multi-objective particle swarm optimization algorithm. Results show the theoretical level of the test adjustments and the influence of the individual pulse parameters to the SE.
