What is it about?
Designing a true cloaking device, allowing an object to be hidden completely, has long been sought after. Here we use the mathematical framework we've used to describe lenses and generalised lenses to show how a cloaking device can be designed. We include a ray tracing simulation of how such a device could perform.

Why is it important?
Cloaks are a fun concept, but realising them is difficult. Here we tried to look at the problem from a new angle and see if it could be done. Hopefully follow on work can develop the components that can make the device a reality.
Perspectives
This work has been the academic interest part of the project I've been working on for the last couple of years. It was a good rest of the mathematical framework we've been developing and also gives us a nice target off in the distance to work towards.
