| Abstract(in English) | Imitated equipment has been used to study the electromagnetic field radiation mechanism from printed circuit board, because the radiated field from imitated equipment with printed circuit board can be calculated and measured. However, the use of the imitated equipment has been limited up to 1GHz caused by its analysis model and operation frequency. In this report, we improve the analysis model and operation frequency to apply the imitated equipment more than 1 GHz, where the newly information technology equipment uses as a clock frequency. The results indicate that the deviation between the calculate and the measurement maximum electric field is within 4 Db for horizontal polarization and within 10 Db for vertical polarization in frequency range of 300MHz-3GHz when we use the segment number of 5591. The investigation also shows that an optical modulator is effective to improve its frequency characteristics. The emission suppression effect by a countermeasure device is evaluated using the improved imitated equipment, and the results indicate that the calculation suppression effect almost agrees with the measured one. |
