Abstract: An electric field intensity calculation apparatus specifies, by analyzing a measurement result for a near magnetic field intensity distribution on a component side of a printed circuit, a maximum intensity of an evaluation target frequency component of a near magnetic field of the printed circuit and an area of a range, on the printed circuit, delimited by using, as its boundary, positions where intensity of the evaluation target frequency component of the near magnetic field attenuates by a predetermined factor relative to the maximum intensity, and calculate a far electric field intensity for the evaluation target frequency at a place at a distance from the printed circuit, based on the area, an electronic current value of an electronic current that generates a near magnetic field having the maximum intensity when flowing through the component side of the printed circuit, the evaluation target frequency, the distance, and a proportional coefficient.

Abstract: A signal transmission cable with a connector, that includes a shielded cable having a shielding layer and an insulating coating layer, which cover a periphery of a plurality of insulated wires, and a magnetic powder compound layer interposed between the shielding layer and the insulating coating layer; a connector which is electrically and mechanically connected to at least one end of the shielded cable, and which has a shielding metal cover extending from a housing part to a cable end, the housing part holding terminals to be connected to the insulated wires; and a closed magnetic path core which is fitted on the shielding layer with the insulating coating layer partly removed at the end of the shielded cable. The shielding layer is folded back so as to cover outside of the closed magnetic path core and a tip portion of the shielding layer is connected to the shielding metal cover.
