Subject: Broadband anti-reflection coatings using “moth-eye” structures in millimeter and submillimeter astronomy

Wasting is evil, let alone wasting the light signal from billions years ago that can potentially reveal the secrets of the Universe. Unfortunately, optical elements in a telescope, such as lenses and filters, reflect part of the light back to sky. In millimeter and submillimeter astronomy, broadband anti-reflection coatings (ARC) are more desired than ever for foreground modeling. In this talk, I will introduce the subwavelength structures (SWS) or so called “moth-eye” structures as an emerging type of broadband ARC in millimeter and submillimeter astronomy.
