Photonic band gaps of optimized crystal and disordered networks

Speaker: Dr. Michael Klatt
Affiliation: FAU, Germany

Meeting ID: 678 8100 6993 , Passcode: 512937

Abstract: The talk will begin with a brief introduction to photonic band gap
materials and standard techniques in the field.
Then, the talk will present two recent discoveries: (1) the first
foam-based photonic heterostructure with a complete photonic band gap
[1], (2) an unanticipated universal behavior in the gap sensitivity of
optimized crystal and disordered networks [2].
The talk will also give a brief outlook on computational challenges and
how novel techniques could lead to answer long-standing problems in physics.
