Summary: These activities guide students through a derivation of the boundary conditions on the electric and magnetic fields at the interface between vacuum and a general material. Initial tasks have them consider the

Consider a Gaussian pill-box at the interface between two different media, arranged as in the figure above. The net enclosed (free) magnetic charge density is zero so as the height of
When an electromagnetic field faces an abrupt change in the permittivity and permeability, certain conditions on electric and magnetic fields on the interface are to be respected for the continuity. These conditions of continuity are known as the boundary conditions for the electromagnetic field. Consider the pillbox in the
these are the sources which are related to the fields which are the electric and magnetic fields. So in general then one can establish relationship between these quantities which we can call as sources to the fields which are electric and magnetic fields and these relationships are called the boundary conditions. So now what
These conditions can be derived from application of Maxwell's equations, Gauss and Stokes. Theorems and have to be satisfied at any materials boundary. 1. n?•(.. B. 2 - B. 1) = 0 ? B = B. 1?. 2?.

and B to their sources, the displacement field D and the magnetic field intensity H. Properties of the propagation media involved are parameterized by (frequency dependent) material constants of linear relations among D and E (D = ?E), and B and H. (B = ?H). Since the boundary conditions are statements of continuity

A very important corollary of this boundary condition is that, since at the surface of a perfect conductor, between any point on or inside the conductor. Therefore, a perfect con- ductor is an equipotential surface. 2. Boundary condition for tangential component of magnetic field: Text, 5-7. The second term on the right hand side
