Modeling photonic crystal fibers

Advances in Applied Mathematics, 2006
The problem indicated in the title gives rise to a Maxwell problem. However, looking for guided waves in the \(x_3\)-direction and assuming the medium to be \(x_3\)-independent, the author is left with two scalar problems with periodic coefficients. The corresponding Green integral operators and their spectral properties are used for a characterization

Tuning the Growth Pattern of Triangular Silver Nanoplates from Lateral to Vertical by Secondary Metal Addition

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
What happens, if in the synthesis of flat silver platelets, the slow deposition of silver along twinning faults is disturbed by the addition of a nobler metal? We have looked into it and found a way to fine‐tune the metal deposition in lateral and vertical direction.
