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…
