Imaging properties of a metamaterial superlens
... It can be seen from Eq. 共6兲 that T P decays exponentially with the increasing thickness d. Thus, for a large mismatch ( 兩 ␦ 兩 ⬎1), the resolution limit as a rule of thumb is ⬃2d. Alternately, when the surface resonance occurs (L ⫹ or L ⫺ →0), the transmission is at a local maximum. Therefore, the ...

Interferometry
Interferometry is a family of techniques in which waves, usually electromagnetic, are superimposed in order to extract information about the waves. Interferometry is an important investigative technique in the fields of astronomy, fiber optics, engineering metrology, optical metrology, oceanography, seismology, spectroscopy (and its applications to chemistry), quantum mechanics, nuclear and particle physics, plasma physics, remote sensing, biomolecular interactions, surface profiling, microfluidics, mechanical stress/strain measurement, and velocimetry.Interferometers are widely used in science and industry for the measurement of small displacements, refractive index changes and surface irregularities. In analytical science, interferometers are used in continuous wave Fourier transform spectroscopy to analyze light containing features of absorption or emission associated with a substance or mixture. An astronomical interferometer consists of two or more separate telescopes that combine their signals, offering a resolution equivalent to that of a telescope of diameter equal to the largest separation between its individual elements.
