On the Numerical Solution of the Near Field Refractor Problem
Cristian E. Gutiérrez, Henok Mawi
A numerical scheme is presented to solve the one source near field refractor problem to arbitrary precision and it is proved that the scheme terminates in a finite number of iterat…

On the Numerical Solution of the Far Field Refractor Problem
Roberto De Leo, Cristian E. Gutiérrez, Henok Mawi
The far field refractor problem with a discrete target is solved with a numerical scheme that uses and simplify ideas from Caffarelli, Kochengin and Oliker. A numerical implementat…
