Author:Litvin, IA; Burger, L; Forbes, ADate:Sep 2013The self-reconstruction of superpositions of Laguerre–Gaussian (LG) beams has been observed experimentally, but the results appear anomalous and without a means to predict under what conditions this take place. In this Letter, we offer a ...Read more
Author:Cilliers, Jacques E; Smit, JC; McDonald, Andre M; Baker, CJ; Woodbridge, KDate:Oct 2012This paper addresses the prediction of the maximum recognition performance of a radar for a predetermined set of targets and radar waveforms. Use is made of the information theoretic concept of mutual information (MI) to perform this analysis. ...Read more
Author:Burger, L; Forbes, ADate:Aug 2008The authors apply a new method of modeling Porro prism resonators, using the concept of rotating loss screens, to study stable and unstable Porro prism resonator. They show that the previously observed petal–like modal output is in fact only ...Read more
Author:Litvin, IA; Burger, L; Forbes, ADate:Oct 2007A new approach to modeling the spatial intensity profile from Porro prism resonators is proposed based on rotating loss screens to mimic the apex losses of the prisms. A numerical model based on this approach is presented which correctly ...Read more
