The Potential Barrier, case E ≥ V₀

In analyzing the situation, we need the transmission and reflection coefficients. Apply the continuity conditions at the points x = 0 and x = a to solve the various intensities of the waves and thereby calculating R and T.

Beware, some heavy rearranging of algebraic expressions ahead. And remember that R + T = 1.
