Groove Geometry Efficiency Calculation 
Given the surface absorption rate, this page presents a method of calculation to determine the efficiency at a number of groove internal angles based on the number of reflections dictated by that angle. The following C program performs these calculations and displays the interior angle, number of reflections, and percentage of incident light absorbed:
