Phys. Rev. Lett. 99, 230401 (2007) [3 pages]Testing Born-Infeld Electrodynamics in WaveguidesReceived 21 August 2007; published 5 December 2007 Waveguides can be employed to test nonlinear effects in electrodynamics. We solve Born-Infeld equations for TE waves in a rectangular waveguide. We show that the energy velocity acquires a dependence on the amplitude, and harmonic components appear as a consequence of the nonlinear behavior. © 2007 The American Physical Society URL:
