Going beyond Axisymmetry: 2.5D Vector Electromagnetics
Urzhumov, YA; Landy, N; Ciraci, C; Smith, DR (2012-10)Linear wave propagation through inhomogeneous structures of size R≫λ (Fig.1) is a computationally challenging problem, in particular when using finite element methods, due to the steep increase of the number of degrees of ... -
Isotropic-medium three-dimensional cloaks for acoustic and electromagnetic waves
Urzhumov, Y; Landy, N; Smith, DR (Journal of Applied Physics, 2012-03-01)We propose a generalization of the two-dimensional eikonal-limit cloak derived from a conformal transformation to three dimensions. The proposed cloak is a spherical shell composed of only isotropic media; it operates in ... -
Relaxation approach for the generation of inhomogeneous distributions of uniformly sized particles
Hunt, J; Kundtz, N; Landy, N; Smith, DR (Applied Physics Letters, 2010-07-12)For many applications in gradient index devices and photonic crystals, it is necessary to be able to design semicrystalline distributions of particles where the lattice constant of the distribution is an arbitrary function ...
