Leontovich boundary condition

The Leontovich boundary condition is a type of boundary condition used in electromagnetic theory, particularly in the context of analyzing wave propagation and scattering in dielectric and conducting materials. It is particularly relevant in scenarios involving surface waves or interfaces between different media. In essence, the Leontovich boundary condition applies to the tangential components of the electric and magnetic fields at the boundary between two different media. Specifically, it provides a way to account for surface impedance at the boundary.
