Analysis of decoupling performances of an isolation barrier using a mode‐matching method

Abstract This paper uses a mode‐matching method to analyze the decoupling performance of an isolation barrier that prevents electromagnetic interference between cables. After dividing overall analyzed space into multiple subregions, potential expressions for each subregion were derived using Laplace equation in conjunction with superposition principle. The Dirichlet and Neumann boundary conditions then applied interfaces subregions compute modal coefficients previously expressions. Based on electric‐field strengths distributions used our testing, geometrical parameters voltage varied find optimal configuration cables maximize performance. performed study is novel informative analysis results provide background determine distances separated by industrial facilities such as nuclear power plants.
