Building 3D models is important in many applications, ranging from virtual visits of historical buildings, game and entertainment, to
risk analysis in partially collapsed buildings. This task is perf...
Efficient computation of equifrequency surfaces and density of states in photonic crystals using Dirichlet-to-Neumann maps
Efficient computation equifrequency surfaces photonic crystals Dirichlet-to-Neumann maps
2015/8/10
We present an efficient method for computing the equifrequency surfaces (EFSs) and density of states of a photonic crystal. The method is based on repeatedly solving a small nonlinear eigenvalue probl...
Experimental Demonstration of XPM Compensation for CO-OFDM Systems with Periodic Dispersion Maps
Fiber optics communications Modulation Nonlinear Optics fibers.
