Maxwell’s equation for any medium is given as:

$∇.\bar{E}=0 –(1) \\ ∇.\bar{H}=0-(2) \\ ∇ ×\bar{E}= -jwμ \bar{H}- (3) \\ ∇ × \bar{H}=(σ+jwε) \bar{E}- (4)$

Consider 4th equation

$∇ × \bar{H }=(σ+jwε) \bar{E}$

Taking cross product on both sides

$∇ × ∇ × \bar{H}= (σ+jwε) ∇ × \bar{E} \\ ∇ (∇.\bar{H …
