How to Calculate Luneburg Lens Refractive Index?
Luneburg Lens Refractive Index calculator uses Luneburg Lens Refractive Index = sqrt(2-(Radial Distance/Radius of Luneburg Lens)^2) to calculate the Luneburg Lens Refractive Index, Luneburg Lens Refractive Index is the gradient refractive index which means it varies with radial distance from the center of the lens. The refractive index is highest at the center of the lens (r=0) and decreases as you move toward the outer edge of the lens. Luneburg Lens Refractive Index is denoted by η_{l} symbol.
How to calculate Luneburg Lens Refractive Index using this online calculator? To use this online calculator for Luneburg Lens Refractive Index, enter Radial Distance (r) & Radius of Luneburg Lens (r_{o}) and hit the calculate button. Here is how the Luneburg Lens Refractive Index calculation can be explained with given input values -> 1.382447 = sqrt(2-(1.69/5.67)^2).
