Band Structure Optimization of Two-dimensional Photonic Crystals in H-polarization
نویسندگان
چکیده
In the study of photonic crystals, the question arises naturally: which crystals produce the largest band gaps? This question is investigated by means of an optimization-based evolution algorithm which, given two dielectric materials, seeks to produce a material distribution within the fundamental cell which produces a maximal band gap at a given point in the spectrum. The case of H-polarization in two-dimensions is considered. Several numerical examples are presented.
