Achievements in PBG structures modelling and fabrication

The engineering of photonic stop-bands and band-gaps is opening up new opportunities in many areas of photonics and optoelectronics. Theoretical modelling as well as experimental research goes in two directions. The first one is analytical, numerical or experimental investigation of reflection and transmission characteristics for special kinds of the structures and by this way an optimization of the structures parameters. The second one is an inverse problem approach using different theoretical and measuring techniques to reconstruct the required geometric and material characteristics, which provide the required optical field transformation
