Finite-difference frequency-domain method for the extraction of effective parameters of metamaterials
Joao T. Costa, Mario G. Silveirinha, Stanislav I. Maslovski
Here, we report a numerical implementation of the nonlocal homogenization approach recently proposed in [M. Silveirinha, Phys. Rev. B 75, 115104 (2007)], using the finite differenc…

Broadband Negative Refraction with a Crossed Wire Mesh
M. G. Silveirinha
It is demonstrated that a structured material formed by nonconnected crossed metallic wires may enable negative refraction over a wide frequency range. This phenomenon is a consequ…

Additional Boundary Conditions for Nonconnected Wire Media
M. G. Silveirinha
Following our recent work [New J. Phys. 10, 053011, (2008)], here we demonstrate that due to strong nonlocal effects additional boundary conditions are essential to characterize th…
