n1=1.6;//core and cladding refractive index of first fiber
n2=1.44;//core and cladding refractive index of second fiber
lamda=0.8;//wavelength of the electromagnetic wave in um
c=(2*%pi)/lamda;//constant value propagation constant
betamax=c*n1;//maximum value of maximum value of beta
betamin=c*n2;//minimum value of minimum value of beta
mprintf("\n Maximum value of Beta is= %.2f rad/um ",betamax);
