A local permittivity model is proposed to accurately characterize spatial dispersion (SD) in nonlocal wire medium (WM) structures with arbitrary terminations. A closed-form expression for the local thickness-dependent permittivity is derived for a general case of a bounded WM with lumped impedance insertions and terminated with impedance surfaces, which takes into account the effects of SD and loads/terminations in the averaged sense per length of the wire medium. The proposed approach results…

A local thickness dependent permittivity model for nonlocal bounded wire medium structures

A thickness dependent permittivity is derived in closed form for bounded wire-medium structures with electrically short wires. The model takes into account spatial dispersion (as an average per

Effects of Spatial Dispersion on Reflection From Mushroom-Type Artificial Impedance Surfaces

In a spatially dispersive medium, the electric dipole moment of an inclusion cannot be related to the macroscopic electric field through a local relation. Several recent works have emphasized the

Strong spatial dispersion in wire media in the very large wavelength limit

It is found that there exist composite media that exhibit strong spatial dispersion even in the very large wavelength limit. This follows from the study of lattices of ideally conducting parallel

The homogenization of composite structures made of long thin metallic wires is an important problem in electromagnetics because they are one of the basic components of the double-negative medium. In
