N2 - In this paper, we show that broadband enhancement of radiation from subwavelength sources can be achieved by using a new type of metamaterials - irregular random wire media (IRWM). In contrast to samples of aligned metal wires, which give a narrowband enhancement at Fabry-Perot resonances, here, the broadband enhancement is achieved due to the internal structure of the sample. Next, in contrast to lenses and hyperlenses, the proposed structure offers this enhancement without enlargement of the radiating aperture.
