Compressive Sensing and Imaging Applications
Compressive sensing (CS) is a new sampling theory which allows reconstructing signals using sub-Nyquist measurements. It states that a signal can be recovered exactly from randomly undersampled data points if the signal ...
Third Harmonic Generation from Aligned Single-Wall Carbon Nanotubes
Optical properties of single-wall carbon nanotubes (SWCNTs) have been extensively studied during the last decade, and much basic knowledge has been accumulated on how light emission, scattering, and absorption occur in the ...
Nonlinear Optical Properties of Highly Aligned Carbon Nanotubes
Through polarization-dependent third hamonic generation experiments done on highly aligned carbon nanotubes on sapphire, the nonzero tensor elements of χ (3) have been extracted. The contribution of the weaker tensor ...
The transition from a TEM-like mode to a plasmonic mode in finite-width THz parallel-plate waveguides
By the near-field measurement of the electric field distribution inside the finite width THz parallel plate waveguide, we find the transition from conventional diffractive TEM-like mode to plasmonic mode. This mode transition ...
