Maximizing bandgaps in two-dimensional photonic crystals: a variational algorithm
Prabasaj Paul, Francis C. Ndi
We present an algorithm for the maximization of photonic bandgaps in two-dimensional crystals. Once the translational symmetries of the underlying structure have been imposed, our…

Bandgap Extremization: Some Exact Results
Prabasaj Paul, Bill Sutherland
We present here a variational method for maximizing the bandgap in a one-dimensional system where the potential is subject to given constraints. Two specific examples are studied i…
