SUMMARY
The transmission coefficient for a finite square barrier is calculated using the formula T = 1/{1+[(V_o ^2)/4E(V_o - E)]sinh^2 (k_2 a)}. In this equation, T represents the transmission probability, V_o is the potential energy of the barrier, E is the energy of the particle, and k_2 is defined as sqrt(2m(V_o - E)/ħ^2). Understanding this formula is crucial for analyzing quantum tunneling phenomena in physics.
