Abstract:
An electromagnetic field intensity computing apparatus for computing an electromagnetic field intensity of an electric circuit device having at least one plate, comprising:a data input unit that receives structure information about the electric circuit device;analysis object dividing means for assigning serial patch numbers to defined patches on the at least one plate;inter-patch regularity detecting means for detecting inter-patch regularity according to the patch numbers assigned by said analysis object dividing means and patch attributes including patch material; andelectromagnetic field intensity computing means for computing the electromagnetic field intensity of the electric circuit device using a moment method according to each mutual impedance by computing the mutual impedance only for a set of patches whose relative positions are unique among sets of patches for which the mutual impedance should be computed, according to the inter-patch regularity detected by said inter-patch regularity detecting means, and by obtaining the mutual impedance between the other sets of patches using the computed mutual impedance.
