| Abstract(in English) | The approximate shielding effectiveness of a plane shield with a dipole source closely placed can be calculated either from Schelkunoff s formula or resistive sheet approximafion.By comparing them with the exact solution,the errors of those approximations are evaluated in connection with the condition of input parameters.The correction factors for those approximated formulas are systematically derived -the formula is first rewritten as function of three non-dimensional parameters,each of which is the function of physical parameters,then the correction factors are presented in a graphical form.By using these correction factors,the rigorous shielding effectiveness,which involves complex integral,can be easily calculated with good accuracy from Schelkunoff s formula or resistive sheet approximation. |
