Calculating coherent optical multiplayer dielectric films

From the Fresnel formula,the expression of single-dielectric film reflectance R and transmittance T are calculated.According to recurrence method,calculating methods of coherent optical multilayer dielectric films are given,which is for the use of calculating reflectance R and transmittance T.The advantage of recurrence method is that it is especially suitable for computer calculation and programming.The iterative formulas will be of practical significance in the calculation of the multilayer dielectric films.
