| Abstract(in English) | A fast algorithm based on a full cavity-mode resonator model of rectangular power-bus structures is able to quickly obtain the power-bus resonance characteristics in multilayer printed circuit boards (PCBs). Furthermore, the approach can provide the resonance characteristics in PCBs with a slit using a slit model expressing electromagnetic coupling across the gap of the slit. However, the model does not express the slit width, which can cause the degradation in accuracy of resonance analysis. In this paper, a slit segment was studied to express the gap of the single slit coupling and analyze the power-bus resonances. The slit segment was given from an equivalent circuit based on a coupled microstrip line. As a result, it was found that the slit segment can provide the power-bus resonance characteristics as accurate as or more accurate than the conventional slit model. |
