A plane wave, y(x, t) = el(kx-wt) (thus y(x)= eikx), is approaching a step potential given by (V=0, x<0), (V=V. >0, x>0). Using the Kline Gordon equation in 1-D, find the transmission and reflection coefficients for when V < E-m. Hint: To include a potential in KG equation, replace idlat with (idla-1), or simply replace E with E-V.
