This work is concerned with the time-harmonic eddy current problem for a medium with a
highly conductive thin sheet. We present asymptotic models and impedance conditions up to
the second order of approximation for the electromagnetic field. The conditions are derived
asymptotically for vanishing sheet thickness ε, where the skin depth is scaled like ε. The first
order condition is the perfect electric conductor boundary condition. The second order
condition is a Poincaré--Steklov map between tangential components of the magnetic field …
