Robustness of One-Dimensional Photonic Bandgaps Under Random Variations of Geometrical Parameters

The supercell method is used to study the variation of the photonic bandgaps in one-dimensional photonic crystals under random perturbations to thicknesses of the layers. The results of both plane wave and analytical band structure and density of states calculations are presented along with the transmission cofficient as the level of randomness and the supercell size is increased. It is found that higher bandgaps disappear first as the randomness is gradually increased. The lowest bandgap is found to persist up to a randomness level of 55 percent.Comment: Submitted to Physical Review B on April 8 200

A Turkish law perspective on the right to be forgotten

Since the rule is changed from easily forget to easily remember thanks to the digital Internet platforms, the question if there should be a right to be forgotten consecrated to individuals has become a frequently asked question with - of -course no “one correct answer” in different legal systems all around the world. Turkish legal practice has also encountered different cases where the question if a right to be forgotten should be recognized/accorded or not. Thus, the concept itself and discussions thereon prove to be heated nowadays among legal scholars. Accord- ingly, this article mainly aims to legally analyze the newly emerging concept “the right to be forgotten” and its potential practical impacts to the existing or future Internet technologies, in light of the Turkish legislations and existing case law
