Infrared non-invasive sub-wavelength microscopy with metamaterials

Sub-wavelength infrared imaging of lipids

Infrared absorption spectroscopy of lipid layers was performed by combining optics and scanning probe microscopy. This experimental approach enables sub-diffraction IR imaging with a spatial resolution on the nanometer scale of 1, 2-dioleoyl-sn-glycero-3-phosphocholine lipid layers.

Far infrared wavelength treatment for low back pain: Evaluation of a non-invasive device.

BACKGROUND Low back pain is a significant cause of lost workplace productivity. Identification of simple, safe, and effective treatment strategies that can be used in the workplace are needed. OBJECTIVE To assess whether far-infrared therapy (FIR) can ameliorate chronic back pain in office workers with the hypothesis that back pain could be effectively treated while at work with minimal inter...

Analytical Modelling of Metamaterials and a New Principle of Sub-wavelength Imaging

Deep sub-wavelength nanofocusing of UV-visible light by hyperbolic metamaterials

Confining light into a sub-wavelength area has been challenging due to the natural phenomenon of diffraction. In this paper, we report deep sub-wavelength focusing via dispersion engineering based on hyperbolic metamaterials. Hyperbolic metamaterials, which can be realized by alternating layers of metal and dielectric, are materials showing opposite signs of effective permittivity along the rad...
