Given that—
E = time and space dependent electric field intensity vector
µ = permeability of the medium
σ = conductivity of the medium
ε = permittivity of the medium
The electromagnetic wave equation is—
-
-
∇2E−μσ ∂E −με ∂2E = 0 ∂t ∂t2 -
∇2E−με ∂E −μσ ∂2E = 0 ∂t ∂t2 -
∇2E−σε ∂E −μσ ∂2E = 0 ∂t ∂t2 -
∇2E− ∂ ∂E − μ ∂2E = 0 μ ∂t ε ∂t2
