Enhanced Self‐Phase Modulation in Silicon Nitride Waveguides Integrated With 2D MoS2 Films

Advanced Materials Technologies, EarlyView.
ABSTRACT On‐chip integration of 2D materials provides a promising route toward next‐generation integrated optical devices with performance beyond existing limits. Here, significantly enhanced spectral broadening induced by self‐phase modulation (SPM) is experimentally demonstrated in silicon nitride (Si3N4) waveguides integrated with 2D monolayer ...

Attenuation Coefficient Measurement in the Thyroid

Journal of Ultrasound in Medicine, 2003
To assess the feasibility of a novel method of measuring the attenuation coefficient in the thyroid, which offers less variability of results than the conventional method.In our new method, the attenuation coefficient was evaluated on the basis of the following equation with sound field correction: alpha = -1/4[Fc(z)-epsilon(z)] x d/dz[log(M0(z))-tau(z)

Mass-attenuation coefficients of beta particles

International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1990
Abstract A method to obtain mass-attenuation coefficients of β particles is described. This method is based upon the simulation of β emission by means of the β energy spectrum. The range of the β particle is chosen as random incidence by means of range distribution of monoenergetic electrons which have the same energy as the β particle.

Relative Spectral Attenuation Coefficients of Water

Applied Optics, 1967
The relative variation of attenuation coefficient with wavelength has been studied in the laboratory for distilled water and seawater. The study was for the purpose of locating any very fine structure in the attenuation vs wavelength curve. The spectral region from 3750 A to 6850 A was examined with 0.2 A resolution; water paths were 9.7 m and 19.5 m ...
