ABSTRACT
The subset of Maxwell’s equations that governs the propagation of electromagnetic waves can be written
∂Ex ∂t = − 1 0
(
jx + ∂Hy ∂z − ∂Hz ∂y
)
, (C.1)
∂Ey ∂t = − 1 0
(
jy + ∂Hz ∂x − ∂Hx ∂z
)
, (C.2)
∂Ez ∂t = − 1 0
(
jz + ∂Hx ∂y − ∂Hy ∂x
)
, (C.3)
∂Hx ∂t =
1 μ0
( ∂Ey ∂z − ∂Ez ∂y
)
, (C.4)
∂Hy ∂t =
1 μ0
( ∂Ez ∂x − ∂Ex ∂z
)
, (C.5)
∂Hz ∂t =
1 μ0
( ∂Ex ∂y − ∂Ey ∂x
)
(C.6)
(Fitzpatrick 2008). Here, E is the electric field-strength, H the magnetic intensity, j the current density (i.e., the current per unit area), 0 the electric permittivity of free space, and μ0 the magnetic permeability of free space.
