Phononic Band Gaps up to relative 8!

This is my presentation of "Parametric Shape Optimization of Lattice Structures for Phononic Band Gaps" I gave at WCSMO-12 June 2017 in Braunschweig.



I'm quite proud of my phononic band gaps up to relative 8 and normalized 1.6.

I already presented the idea at ECCOMAS 2016 in Crete but there I made the embarrassing mistake of not enforcing square symmetry. However this is a non that uncommon mistake I meanwhile learned. Also my results are much better now.
