Phys. Rev. Lett. 95, 031301 (2005) [4 pages]Hawking Radiation in an Electromagnetic Waveguide?Received 23 August 2004; published 15 July 2005 It is demonstrated that the propagation of electromagnetic waves in an appropriately designed waveguide is (for large wavelengths) analogous to that within a curved space-time—such as around a black hole. As electromagnetic radiation (e.g., microwaves) can be controlled, amplified, and detected (with present-day technology) much easier than sound, for example, we propose a setup for the experimental verification of the Hawking effect. Apart from experimentally testing this striking prediction, this would facilitate the investigation of the trans-Planckian problem. © 2005 The American Physical Society URL:
