The column headings from left to right are as follows: Field components, general form, medium 1 dielectric, medium 2, dielectric, and medium 1, dielectric, medium 2, conductor. The conditions are follows:

- Field component, tangential E. General form, n sub 2 caret cross left parenthesis E sub 1 minus E sub 2 right parenthesis equals 0. Medium 1 dielectric, medium 2, dielectric, E sub start expression 1 t end expression equals E sub start expression 2 t end expression. Medium 1 dielectric, medium 2 conductor, E sub start expression 1 t end expression equals E sub start expression 2 t end expression equals 0.

- Field component, normal D. General form, n sub 2 caret dot left parenthesis D sub 1 minus D sub 2 right parenthesis equals rho sub s. Medium 1 dielectric, medium 2, dielectric, D sub start expression 1 n end expression minus D sub start expression 2 n end expression equals rho sub s. Medium 1 dielectric, D sub start expression 1 n end expression equals rho sub s. Medium 2 conductor, D sub start expression 2 n end expression equals 0.

- Field component, tangential H. General form, n sub 2 caret cross left parenthesis H sub 1 minus H sub 2 right parenthesis equals J sub s. Medium 1 dielectric, medium 2, dielectric, H sub start expression 1 t end expression equals H sub start expression 2 t end expression. Medium 1 dielectric, H sub start expression 1 t end expression equals J sub s. Medium 2 conductor, H sub start expression 2 t end expression equals 0.

- Field component, Normal B. General form, n sub 2 caret dot left parenthesis B sub 1 minus B sub 2 right parenthesis equals 0. Medium 1 dielectric, medium 2, dielectric, B sub start expression 1 n end expression equals B sub start expression 2 n end expression. Medium 1 dielectric, medium 2 conductor, B sub start expression 1 n end expression equals B sub start expression 2 n end expression equals 0.
