Non-magnetic negative-refraction systems for terahertz and far-infrared frequencies
Leonid V. Alekseyev, Viktor A. Podolskiy, Evgenii E. Narimanov
We demonstrate that homogeneous naturally-occurring materials can form non-magnetic negative refractive index systems, and present specific realizations of the proposed approach fo…
Super-resolution imaging via spatiotemporal frequency shifting and coherent detection
Leonid Alekseyev, Evgenii Narimanov, Jacob Khurgin
Diffraction limit is manifested in the loss of high spatial frequency information that results from decay of evanescent waves. As a result, conventional far-field optics yields no…
Super-resolution Spatial Frequency Differentiation of Nanoscale Particles with a Vibrating Nanograting
Leonid Alekseyev, Evgenii Narimanov, Jacob Khurgin
We propose a scheme for detecting and differentiating deeply subwavelength particles based on their spatial features. Our approach combines scattering from an ultrasonically modula…
Optical Hyperlens: Far-field imaging beyond the diffraction limit
Zubin Jacob, Leonid V. Alekseyev, Evgenii Narimanov
We propose an approach to far-field optical imaging beyond the diffraction limit. The proposed system allows image magnification, is robust with respect to material losses and can…
Strongly anisotropic media: the THz perspectives of left-handed materials
Viktor A. Podolskiy, Leo Alekseev, Evgenii E. Narimanov
We demonstrate that non-magnetic () left-handed materials can be effectively used for waveguide imaging systems. We also propose a specific THz realization of the non-ma…
