Abstract Title: W06 - Multidirectional Invisibility with Rays of Light - a “Rochester Cloak”
Abstract: In this workshop, students will be able to use and explore a few versions of the "Rochester Cloak," which uses off-the-shelf optical lenses only. They will be able to make part of their hand or other small objects become invisible and explore the cloaking regions of the devices. Additional hands-on experience will be provided, where students can test the sensitivity of the lens alignments, by changing one of the lenses to view magnification, chromatic, and positional mismatches from the background.

In addition, participants will learn how to define an invisibility cloaking device with simple matrices, using geometrical optics. A brief description of "ABCD matrices" for lenses and propagation will be taught. Thus, participants will learn an introductory set of tools to design their own cloaking devices, limited to the 'paraxial' (small range of angles) regime.
