# Propagation Constant Formula

Propagation Constant for an electromagnetic wave is represented as

$Propagation\,constant(\gamma )=\frac{Complex\,Amplitude\,at\,the\,source\,of\,the\,wave\,(A_{0})}{Complex\,Amplitude\,at\,the\,distance\,x\,(A_{x})}$

Where,

$\frac{A_{0}}{A_{x}}=e^{\gamma x}$

Propagation constant

$\gamma =\alpha +i\beta$ $\alpha =\,real\,part\,of\,attenuation\,constant$ $\beta =imaginary\,part\,of\,phase\,constant$
