An isotropic plasma is composed of free charge carriers. Wire medium is an artificial plasma that is constructed by aligning conducive wires in one-, two-, or three dimensions (see e.g. [1]). In the simplest form, that is the one-dimensional case, the wires are aligned in parallel with a certain lattice constant. In more complicated two- and three-dimensional wire media the wires are aligned in a similar way in parallel in two or three orthogonal directions, respectively. Unlike in the gas-like plasma, the electromagnetic properties of this artificial plasma are constrained by its geometrical structure. Such constrains are, for instance, anisotropy and spatial dispersion.
