Broadband, millimeter-wave anti-reflective structures on sapphire ablated with femto-second laser
R. Takaku, S. Hanany, H. Imada +13
We designed, fabricated, and measured anti-reflection coating (ARC) on sapphire that has 116% fractional bandwidth and transmission of at least 97% in the millimeter wave band. The…
