The magnetically controlled planar hyperlens which consists of an InSb-PMMA multilayered structure is proposed and analyzed. The ability of the proposed hyperlens to resolve subwavelength structures at THz region is demonstrated by electromagnetic numerical simulation. The asymmetric field pattern in the hyperlens is caused by the surface magnetoplasmon (SMP) propagating in the InSb-PMMA waveguide. By using transfer matrix method and the effective medium approach of the investigated components, the role of SMP played in the super-resolution is elucidated. Furthermore, the super-resolution of the proposed device under various frequencies is accomplished by merely changing the value of external magnetic field. The proposed device would provide a practical route for multi-functional material, real-time super-resolution imaging, photolithography, and THz imaging.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
