Electromagnetic Interference Mitigation Using Guiding Conductive Strips

In this paper, a guiding conductive strip is proposed to provide EMI protection for small modular reactors based on digital technology. We employ the mode-matching method to analyze the decoupling performance of the proposed guiding conductive strip. Using the validated mode-matching method, we derive the optimal location of the guiding conductive strip to confine the undesired electromagnetic influence by using the capacitance matrix as the figure of merit. We also interpret the operating principle of the proposed guiding conductive strip by analyzing the electric field strength distribution. The performed mode matching analysis for the guiding conductive strip provides useful information to mitigate the electromagnetic interference in the modernized nuclear power plants, such as a small modular reactor.
