// Given data
VSWR = 3; // voltage standing wave ratio
d = 20*10^-2 // separation b/w 2 successive minimas
er = 2.25; // dielectric constant
v = 3*10^8; // velocity in m/s
// Calculations
// VSWR = (1 + p)/(1 - p)
p = (VSWR -1)/(VSWR + 1); // reflection co-efficient
lamda = 2*d; // wavelength of tx line
lamda_fr= lamda*sqrt(er); // free space wavelength
f = v/lamda_fr; // operating frequency in Hz
// output
