April
The yearly OWTNM workshop has, since 1992, provided a forum for lively debates, intended to bring forward new ideas in the field of theoretical and computational photonics. Basic physics and novel applications, artificially structured materials and new devices, elegant mathematical techniques and efficient numerical methods to tackle the Maxwell equations form the constantly evolving subjects. These are discussed in a traditionally open and relaxed atmosphere.
