Alkanethiol-capped gold nanoparticles dispersed in n-dodecane were studied by spectroscopic ellipsometry and were modeled using Mie scattering theory. The refractive index in the visible and near-infrared depended on the volume fraction of gold nanoparticles, in good agreement with the theoretical expectation that such dispersed plasmonic nanoparticles can act as low or tunable refractive index...
Scattering by microscopic particles renders virtually all dusty surfaces brighter than dust-free surfaces. Examples of surface brightening are demonstrated in the landscape and laboratory and explained theoretically using Mie theory calculations. The implications for landscape photography and remote sensing are discussed.
The finite-difference time-domain (FDTD) technique is used to compute light scattering from biological cells in two dimensions. Results are presented for the computed scattering patterns of cells containing multiple organelles. This method provides considerably more flexibility than Mie theory because of its ability to model inhomogeneous objects such as cells. © 1997 Society of Photo-Optical I...
The mode spectrum of a 3.8-cm-diameter fused-silica sphere has been studied in the vicinity of 1.06 microm. A single-frequency Nd:YAG laser was used to excite whispering gallery modes by means of evanescent wave coupling. The spectrum is in excellent agreement with predictions from Mie theory.
Only a few series have demonstrated the safety and efficacy of minimally invasive esophagectomy (MIE) for esophageal squamous cell carcinoma and the benefits of this approach. This report describes the results of a pair-matched comparative study between minimally invasive and open esophagectomy (OE) for esophageal squamous cell carcinoma. Patients were retrospectively matched in pairs for the f...
BACKGROUND Pulmonary complications (PCs) after esophagectomy for patients with esophageal cancer have been correlated with prolonged hospital stays and in-hospital mortality. Previous studies have shown that minimally-invasive esophagectomy (MIE) is associated with a lower rate of PCs compared to conventional open surgery. Although PCs were reportedly associated with many factors, including sur...
The effect that geometrical resonances of orbiting internally reflecting rays have on the morphology-dependent resonances of microspheres is investigated heuristically and numerically using generalized Lorenz-Mie theory. Angularly resolved off-axis Gaussian beam elastic scattering spectra are presented. The results obtained show that the elastic scattering intensity of morphology-dependent reso...
We introduce an inverse method for determining simultaneously the real and imaginary refractive indices of microspheres based on integrating sphere measurements of diffuse reflectance and transmittance, and Monte Carlo modelling in conjunction with the Mie theory. The results for polystyrene microspheres suspended in water are presented.
