Seamless Integration of Global Dirichlet-to-Neumann Boundary Condition and Spectral Elements for Transformation Electromagnetics
Zhiguo Yang, Li-Lian Wang, Zhijian Rong +2
In this paper, we present an efficient spectral-element method (SEM) for solving general two-dimensional Helmholtz equations in anisotropic media, with particular applications in a…

Accurate Simulation of Ideal Circular and Elliptic Cylindrical Invisibility Cloaks
Zhiguo Yang, Li-Lian Wang
The coordinate transformation offers a remarkable way to design cloaks that can steer electromagnetic fields so as to prevent waves from penetrating into the {\em cloaked region} (…
