Static Electric Fields

The electric field component of a plane wave in a certain lossy medium is given by

$\vec{E}=25 e^{\frac{-z}{50}} \cos \left(1.5 \times 10^{8} t-2 \pi z\right) y V / m$ . The propagation constant ( in m^–1) of the medium is given by?

$0.12+j 4 \pi$

$0.2+j 2 \pi$

$true$

$0.02+j 2 \pi$
