Microwave Focusing by a Wire Medium

摘要

Through numerical simulation, the present paper demonstrates the ability of a wire medium to focus microwave radiation in the 8-14 GHz frequency range. Microwave focusing is achieved in a small volume to produce localized energy dissipation processes and high-temperature gradients. The wire medium is implemented with 0.5-mm-diameter metallic wires symmetrically arranged in a square lattice with spacing constant of 10.0 mm.
