Thesis abstract:

Hyperbolic metamaterials, due to their extraordinary optical properties have gained much attention in the scientific community, in particular for imaging to beat the diffraction limit. A special class of hyperbolic metamaterial is the wire medium (WM), comprising of subwavelength array of metal wires hosted within a dielectric. From radio to infrared frequencies, WM possess hyperbolic dispersion relation and this specific property allows them to support the high spatial frequency propagating waves, consequently beating the diffraction limit. Endoscopes and hyperlenses based on WM can resolve subwavelength features far below the diffraction limit, however, images from them are not perfect, as a consequence limits the use of the hyperlenses for broad-band subwavelength devices. Using finite integral based software (CST) we numerically study sources of imaging artefacts for endoscopes (no-magnifying hyperlens) and magnifying hyperlens, and present post-processing methods to eliminate them so that better imaging can be achieved in the entire band of interest.
In addition, we fabricate a magnifying WM prism hyperlens at THz frequencies using the fiber drawing technique. Most previous designs in magnifying hyperlenses rely on either curved geometry or tapering of the medium. One of the main issues of such hyperlenses is the difficulty of manufacturing, however, using the prism structure the fabrication difficulties can be minimized. We experimentally characterize the transmission properties of the hyperlens using THz time-domain spectroscopy, and also show that our device can resolve feature sizes far below the diffraction limit with two-fold magnified image at the output. However, the hyperlens shows strong frequency dependent artefacts, which is due to the resonances of the individual wires. We show that the resonant behaviour of the individual wires can be eliminated using spatially varying time gating or frequency convolution, yielding broad-band imaging.
