Postdoctoral Position (May 5, 2023)
Soot Absorption Cross Section Measurements
Kansas State University - Physics
A postdoctoral position is now open to perform experiments to measure and understand the absorption cross section of soots formed from detonations. This work will be done in the near infrared (NIR). Methods will involve dispersion of soots as aerosols and as suspensions in liquids with known refractive index. Then transmission of light through the sol will be measured. These measurements will be augmented with both static and dynamic light scattering measurements to characterize the size and morphology of the suspended particles. Corrections for the medium refractive index will be developed. Studies of the effects of source, size and morphology will be performed. There will be strong theoretical support via collaboration with another scientist. Applicants should have strong experimental skills in optics, problem solving, and understanding experimental results. This position could start immediately, and funding is ensured to the end of calendar 2024.

CDPDS Coupled dipole method-based photonic dispersion solver
A photonic band dispersion solver based on the coupled dipole method called CDPDS, which aims to provide an analytical computation of bulk and boundary dispersions and topological phases of a one-dimensional and two-dimensional photonic crystal consisting of an array of particles.
RETOP
RETOP is an free Matlab toobox that implements a near-to-far-field transformation for computing the radiation diagram. RETOP operates for objects on substrates or buried in stratified media.

TransitionMatrices.jl
The Julia package `TransitionMatrices.jl` by Zihua Wu implements the classic EBCM method, supporting arbitrary precision and automatic differentiation. To calculate the T-Matrix of various types of scatterers the EBCM and the Invariant Imbedding T-Matrix Method (IITM) is implemented.
