The column headings from left to right are field component, any two media, medium 1 Dielectric epsilon sub 1 and medium 2 conductors. The table information is as follows:

- Field component, Tangential E. Any two media, E sub start expression 1 t end expression equals E sub start expression 2 t end expression. Medium 1 Dielectric epsilon sub 1 and medium 2 conductors, E sub start expression 1 t end expression equals E sub start expression 2 t right expression equals 0.

- Field component, Tangential D. Any two media, start fraction D sub start expression 1 t end expression over epsilon sub 1 end fraction equals start fraction D sub start expression 2 t end expression over epsilon sub 2 end fraction. Medium 1 and medium 2, D sub start expression 1 t end expression equals D sub start expression 2 t end expression equals 0.

- Field component, Normal E. Any two media, epsilon sub 1 E sub start expression 1 n end expression minus epsilon sub 2 E sub start expression 2 n end expression equals rho sub s. Medium 1, E sub start expression 1 n end expression equals start fraction rho sub s over epsilon sub 1 end fraction. Medium 2, E sub 2 n equals 0.

- Field component, Normal D. Any two media, D sub start expression 1 n end expression minus D sub start expression 2 n end expression equals rho sub s. Medium 1, D sub start expression 1 n end expression equals rho sub s. Medium 2, D sub start expression 2 n end expression equals 0.
