Body with mirror surface and connected interior invisible from one point

TL;DR

This paper demonstrates the existence of a piecewise smooth obstacle with a connected interior that remains invisible from a specific point using geometric optics principles.

Contribution

It introduces a novel obstacle design with a connected interior that is invisible from a point, advancing the understanding of invisibility in geometric optics.

Findings

Existence of such obstacles proven.

Obstacle design with connected interior achieved.

Invisibility from a point demonstrated.

Abstract

Here we demonstrate existence of a piecewise smooth obstacle having connected interior and invisible from a point in the framework of geometric optics.
