Linearly polarized light is the sum of two circular polarizations, in order to get one circular polarization, the second one should be suppressed. By means of reflection it is possible to suppress only one linear polarization (reflection at the Brewster angle), that is why it is impossible to turn light into polarized along the right circle by a single reflection.
The circle can be obtained only by passing through a quarter wave plate.
I'm extremely impressed with your work. In fact, I am likely going to change major to computer science from next semester. Before turning to you for help, I thought its all over and there is simply no one who can offer expert programming help. I had no hope at all. My experiences with other sites were horrible.
By chance I contacted you about 7 months back and it was amazing when I looked at your work. From thereon, I decided to rely on you only.
