| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The purpose of this study is to make clear the suppression effect and invasiveness of the near electromagnetic field by the conductor or magnetic material put on the PCB. The suppression effect and invasiveness by the copper plate, ferrite plate and composite material pasted the copper and ferrite plates together are discussed by the measurement and calculation. The suppression effect by the copper plate increases as the frequency is higher. The suppression effect by the ferrite plate is corresponded to the frequency characteristics of permeability of the ferrite. The suppression effect by the composite suppression material is large than that of the copper or ferrite plates by itself at all frequency band. As the invasiveness for the near electromagnetic field by the FDTD is calculated, it is appeared that the invasiveness for the near magnetic field is large. As the composite material (mc) that the magnetic material is PCB side puts on the PCB, the invasiveness with the electric field between PCB and composite material is small. | |
