Admittance matching is generally used in the design of optical components which require in the same time high reflectance and high transmission bands. The matching is done at the both sides of the basic stack by synthesizing an equivalent layer with symmetrical three layer periods. In order to obtain a broad transmission band, a quasi-matching is necessary around the matching wavelength. The paper studies the solutions provided by analytical synthesis of the matching stack for a number of one to three periods.
