Thin Shell Model of a Coated Conductor With a Ferromagnetic Substrate

Coated conductors with magnetic substrates are thin multilayer structures; their high aspect ratio and nonlinear material properties present significant difficulties for numerical simulation. Using the width-to-thickness of coated we derive an integral formulation a model based on infinitely approximation superconducting layer quasistatic shell substrate. The proposed describes electromagnetic response conductor substrate is much simpler than existing models. A single dimensionless parameter characterizes having finite permeability thickness. An accurate efficient Chebyshev spectral method derived solution. influence current ac losses investigated. In limiting cases our solution tends to known analytical solutions.
