I am trying to optimize the pillar height, radius and pitch of the attached structure where it will have to show the minimum reflection and maximum absorption at the wavelength (350 to 900).

(1) If I want to sweep the pitch and observe the reflection at the wavelength (350nm to 900nm), do I need to take 2 pillars inside a unit cell?
In the website, they optimized a parameter( thickness of a material) with respect to reflection. The thickness that has the minimum reflection. But it has considered only one particular wavelength (like 550nm). But I want to have my answers like the one below.
