Abstract:
The restrictions on the resolution of transmission devices formed by wire media (arrays of conductive cylinders) recently proposed in Phys. Rev. B 71, 193105 (2005) and experimentally tested in Phys. Rev. B 73, 033108 (2006) are studied in this paper using both analytical and numerical modeling. It is demonstrated that such transmission devices have subwavelength resolution that can in principle be made as fine as required by a specific application by controlling the lattice constant of the wire medium. This confirms that slabs of the wire medium are unique imaging devices at the microwave frequency range, and are capable of transmitting distributions of TM-polarized electric fields with nearly unlimited subwavelength resolution to practically arbitrary distances.
