A Hybrid Radial Basis Function - Pseudospectral Method for Thermal Convection in a 3-D Spherical Shell

, 2009
A novel hybrid spectral method that combines radial basis function (RBF) and Chebyshev pseudospectral (PS) methods in a “2+1” approach is presented for numerically simulating thermal convection in a 3-D spherical shell.

Angle-Resolved Structural Coloration Modeling in Morpho Wing Nanostructures With Staggered 3D Pseudospectral Time-Domain Method

IEEE Photonics Journal
This work presents a three-dimensional (3D) staggered pseudospectral time-domain (PSTD) framework for modeling the structural coloration of Morpho butterfly wings. Compared with finite-difference time-domain (FDTD) methods, the PSTD algorithm reduces the
