Active multilayer mirrors for reflectance tuning at extreme ultraviolet (EUV) wavelengths [PDF]

open access: yes, 2012
We propose an active multilayer mirror structure for EUV wavelengths which can be adjusted to compensate for reflectance changes. The multilayer structure tunes the reflectance via an integrated piezoelectric layer that can change its dimension due to an
