T-typed photonic crystal circulator with square lattice Al2O3 rods array and NiZn-ferrite posts
Materials & Design, 2019 This paper proposes and validates a novel T-typed magneto-photonic crystals circulator consisting of Al2O3 ceramic rods array and ferrite posts. Based on the numerical simulations on the band gap of photonic crystals and the function of the circulator ...

A geometry optimization framework for photonic crystal design
, 2012 The performance of photonic crystal devices can depend strongly on their geometry. Alas, their fundamental physics offers relatively little by way of pointers in terms of optimum shapes, so numerical design search techniques must be used in an attempt to

The influence of fabrication deviations on the photonic band gap of three-dimensional inverse woodpile nanostructures [PDF]
, 2009 The effects of unintended deviations from ideal inverse woodpile photonic crystals on the photonic band gap are discussed. Such deviations occur during the nanofabrication of the crystal.

Exciton Binding Energy of Phosphorescent Emitter Molecules in Organic Light‐Emitting Diodes
Advanced Functional Materials, EarlyView.Energy level alignment is key to efficient OLED design, yet determining LUMO energies remains challenging. A methodology based on field‐induced dissociation and kinetic Monte Carlo simulations is presented to extract LUMO energies of iridium‐based phosphorescent emitters from their exciton binding energy.
