Mo/Si aperiodic multilayer broadband reflective mirror for 12.5–28.5 nm waveleng

Aperiodic molybdenum/silicon (Mo/Si) multilayer designed as a broadband reflective mirror with mean reflectivity of 10% over a wide wavelength range of 12.5–28.5 nm at incidence angle of 5? is developed using a numerical optimized method. The multilayer is prepared using direct current magnetron spu
