| Abstract(in English) | To clarify the noise radiation around the PCB with a switching circuit, the distribution of the electric and magnetic field from 0.1 to 3 m are estimated by the developed FDTD-Multiple Analysis Space (FDTD-MAS) method. The FDTD-MAS method is an analysis technique for wide spatial area combined by the multiple analysis spaces composed with the difference cell size. At 10 cm from PCB, the electric and magnetic field strength at fundamental frequency, 3 MHz, is larger than the higher frequency. The 3 MHz component decreases as the distance for x-direction from PCB increases. At the 3 m from the PCB, the electromagnetic field at 500 MHz, which is the resonance frequency for the longitudinal direction of the PCB, is the largest. As the electric field spectra at horizontal component by the FDTD-MAS method and measurement in an anechoic chamber are similar in 6 dB, the utility of the simulation method for the distribution of the electromagnetic field at wide area using the FDTD-MAS method is confirmed. |
