sqrt(R)*(cos a + i sin a) = (n - ik - 1) / (n - ik + 1)
what is n in terms of others.
"i" is imaginary part.
By using this equation, can you separate imaginary and real part for finding
R= (1-R) / [1+R-2*sqrt(R) * cos a] and
K = 2 * sqrt(R) * sin a / [1 + R - 2 * sqrt (R) * cos a ]
The Attempt at a Solution
i have found n iK + [ (1+sqr(R) * (Cosa+isina) ]/[(1-sqr(R) * (Cosa+isina)]
but i couldn't separete imaginary and real parts.
if i separeta n has not imaginary part. by using this info. we can gain K.
