Design and Numerical Analysis of an Infrared Cassegrain Telescope Based on Reflective Metasurfaces
Reflective imaging systems such as Cassegrain-type telescopes are widely utilized in astronomical observations. However, curved mirrors in traditional Cassegrain telescopes unavoidably make the imaging system bulky and costly. Recent developments in the field of metasurfaces provide an alternative w...
