Multislice does it all-calculating the performance of nanofocusing X-ray optics.
Optics Express, 2017 We describe an approach to calculating the optical performance of a wide range of nanofocusing X-ray optics using multislice scalar wave propagation with a complex X-ray refractive index. This approach produces results indistinguishable from methods such
