Example

For a medium with $=15{10}^{-3}\frac{S}{m},{}_r=4,{}_r=18$ with a magnitude of electric field intensity $E=10e^{-x}\frac{V}{m}$ at the transmitter point and the frequency $f=20$ MHz$..$ Find:

i$.$ The attenuation constant

ii$.$ The phase shift coefficient

iii. The propagation phase velocity

iv$.$ The electric field intensity at a distance of $x=1000m$ from the transmitter.
