Magnetic field controlled laser diffraction in a thin film of ferrofluid. In this work, we presented a phenomenological model for the light pattern formation observed in a thin film of ferrofluids based on the Geometrical Theory of Diffraction and hyperbolic geometry. More information about this system can be found in this paper "Horocycles of Light in a Ferrocell" https://www.mdpi.com/2410-3896/6/3/30

Levitation illusion
Levitation illusion

Demonstration of levitation illusion using a mirror at New York Hall of Science. In Brazil, we’ve perceived that there is resistance to the learning of Optics by students who are not from the area of physics. The traditional way of teaching optics requires a prior knowledge of calculus that is not easy for students of the natural sciences. In order to solve this problem, we have developed an experimental optics discipline for undergraduate students in nature sciences: Concepts in Experimental Optics. More about this work can be found in this paper: Some remarks of teaching "The Concepts in Experimental Optics" for students in natural sciences in Brazil
