Question

write down the boundary conditions to be satisfied by electromagnetic waves across a boundary.​

Answer 1

Answer:

We can derive “boundary conditions” on the electric and magnetic fields (i.e. relationships between the electric and magnetic fields on either side of a boundary) from Maxwell's equations. These boundary conditions are important for understanding the behaviour of electromagnetic fields in accelerator components.

Answer 2

Answer:

Integrate over the volume of the pillbox, and apply Gauss' ... magnetic fields at the surface of a good conductor can be written: B1n. ≈ 0. B2n ... Applied to waves, the boundary conditions on the fields lead to.
