Astrometric detection of exoplanets in face-on orbits using vortex filters
Niña Zambale Simon, Miguel Revilla, Nathaniel Hermosa
We propose a method to detect exoplanets based on their host star's intensity centroid after it passes thru a vortex filter. Based on our calculations with planets in face-on orbit…

A paraxial cloak with four lenses of different focal lengths
Miguel Revilla, Joshua Cesar Lorenzo, Nathaniel Hermosa
We demonstrate cloaking with four lenses of different focal lengths. To achieve this, we compute the separation distances between lenses such that the effective ABCD matrix is equa…
